A bag contains 10 red marbles and 5 blue marbles. You randomly select 3 marbles from the bag. What is the probability that all 3 marbles are blue when (a) you replace each marble before selecting the next one and (b) you do not replace each marble before selecting the next one?

(a) 1/3 (b) 1/3
(a) 1/27 (b) 1/3
(a) 1/27 (b) 2191
(a) 1/3 (b) 2/91​

Answers

Answer 1

Answer:

A.) With replacement = 1/27

B.) Without replacement = 2/91

Explanation:

Given the following :

Red marbles = 10

Blue marbles = 5

Probability that all 3 marbles are blue;

A.) With replacement :

Total no marbles = 10 + 5 = 15

P(First pick equals blue) = 5/15 = 1/3

P( second pick equals blue) = 5/15 = 1/3

P( third pick equals blue) = 5/15 = 1/3

P(blue blue blue) = (1/3) × (1/3) × (1/3) = 1/9

B.) Without replacement :

P(First pick equals blue) = 5/15 = 1/3

P( second pick equals blue) = 4/14

P( third pick equals blue) = 3/13

P(blue blue blue) = (1/3) × (4/14) × (3/13 )

= 12/546 = 2/91

Answer:

The correct answer to the following question will be "group think".

Explanation:

Group thinking seems to be a psychological condition occurring within such a community of individuals, wherein the community's ambition for unity or adherence leads to an inaccurate decision-making consequence.It is also characterized by offender dehumanization, a perception of invincibility as well as an unethical or unreasonable judgment-making process.

So that the given scenario is the example of group think.

This situation exemplifies "groupthink" as Cedrick, the restaurant's floor manager, proposed an idea, and without discussion, the staff quickly agreed and implemented it, potentially leading to poor decision-making.

This situation is an example of "groupthink." Groupthink occurs when a group of people quickly agrees with a proposed idea or decision without critically evaluating it. In this case, Cedrick, as the floor manager, shared his idea with the staff, and without much discussion or independent thinking, everyone agreed and implemented the idea.

Groupthink can be problematic because it can lead to poor decision-making as important perspectives or alternative solutions may not be considered. It's generally important for groups to encourage open and constructive discussion to avoid falling into the trap of groupthink and to make more informed decisions.

what invention in the 1400s most directly contributed to the increase in the number of active printers in Europe in 1500s

Answers

Martin Luther and the 95 theses which led to the Protestant Reformation or simply put, the wood block printing press

Final answer:

The printing press, invented by Johannes Gutenberg in the 1400s, significantly increased the number of active printers in the 1500s and played a crucial role in the cultural and intellectual developments of the Renaissance and the Protestant Reformation.

Explanation:

The invention in the 1400s that most directly contributed to the increase in the number of active printers in Europe in the 1500s was the printing press, invented by Johannes Gutenberg. Gutenberg's innovative technology allowed for the mass production of printed material and prompted a significant rise in literacy and the dissemination of ideas across Europe. By the end of the 15th century, almost every large European city had at least one printing press, with Venice becoming the printing capital. The printing revolution that followed led to greater distribution of books, fostering the spread of Renaissance humanism, skepticism, and even contributing to the Protestant Reformation.

Various interpretations are given to people's behaviour and social interaction is berth as a result of these interpretations.

Example is when people who are addicted to smoking continues to smoke despite medical advice that smokers are liable to die young. The general belief of these smokers is that it is no big deal smoking, meaning it is cool.

What caused the Dust Bowl?

Describe the impact of the Civilian Conservation Corps in Texas during the Great Depression in the 1930s.

can someone answer both please

Answers

Answer:

The answer is below

Explanation:

1. Dust bowl was caused by strong winds, drought and clouds of dust, which was as a result of persistent dry weather that caused crops to fail, leaving the plowed fields exposed to wind erosion.

It was around 1931 to 1939, when about 75 percent of United States was plagued with Dust bowl.

2. Civilian Conservation Corps, or CCC, was established by then United States President, Franklin D. Roosevelt on April 5, 1933. A part of his New Deal legislation, whose purpose is to reduce the high unemployment during the Great Depression by ensuring that thousands of young men were employed on environmental conservation projects.

The CCC developed 56 state, national and local parks in Texas during the period of 1933 till 1942. Thirty-one of these are present in the Texas Parks & Wildlife Department. Other parks serve the public in cities and counties around the state.

In the end, CCC was credited to have planted more than 3.5 billion trees on land made barren from fires, natural erosion, intensive agriculture or lumbering.

Which statement best demonstrates an effect of global trade?
A.
Saudi Arabia sells less oil.
B.
Europeans form political parties.
C.
The United States conducts elections.
D.
People in Africa wear blue jeans.

Answers

Final answer:

The best demonstration of the effect of global trade is 'People in Africa wear blue jeans,' indicating that globalization has facilitated cultural exchanges and the distribution of goods globally. Global trade has profound impacts on economies, industries, and consumers around the world, often leading to an increased variety of products and cultural influences while also carrying potential drawbacks.

Explanation:

The statement that best demonstrates an effect of global trade is D. People in Africa wear blue jeans. This phenomenon exemplifies how globalization has allowed for the wide distribution of goods like clothing, leading to cultural exchanges and the adoption of styles across different countries. The presence of blue jeans, typically a Western garment, in Africa indicates that trade has made these items accessible globally, and reflects the influence of Western culture as a result of trade.

Global trade has numerous effects on economies and societies. In the context of globalization, the reduction of trade barriers such as tariffs and quotas, alongside improvements in transportation and communication technologies, have significantly increased the movement of goods, services, and cultures around the world. Consumers benefit from a greater variety of products, often at lower prices, while businesses that can produce superior or more cost-effective products can expand their markets internationally.

However, global trade can also lead to negative consequences such as environmental degradation and uneven wealth distribution. It can also impact local industries due to increased competition, which may lead to job losses or reduced wages in particular sectors. The ability of international trade to serve as a counterweight to protectionist domestic interests, nevertheless, suggests that there are political as well as economic dimensions to these effects.

b
There is no difference in meat consumption between developed and developing nations.
c
There is more meat consumed in developing nations.
d
The more developed a nation is, the more meat is consumed by people.

Answers

Answer: d .The more developed a nation is, the more meat is consumed by people.

Explanation:

Today, majority of people all over the world are dependent upon meat based diet. The meat based diet meets the daily protein needs of people thus people try to consume meat as much as possible. The meat yield depends upon efficiency of poultry farming, cattle farming and biotechnology of the country. The diseased animals are likely to reduce the meat yield hence, medical and biotechnology is required to reduce the problems associated with meat yielding animals. Also a technology is required to yield more meat in animals. Thus a developed nation is expected to overcome meat related problems, hence, more meat will be consumed by the people belonging to developed nation.

If a credit card balance is paid in full within the grace period then the customer will receive __________. A. Lower interest rates B. Unlimited credit C. No finance charges D. Higher interest rates Please select the best answer from the choices provided A B C D

Answers

Answer: A

Explanation:

Lower interest rates apply to credit card balances that are paid in full within the grace period for that card. As a result, choice (A) is the best way to respond.

What is credit card?

A credit card is a payment card given to customers (cardholders) that enables the user to pay a merchant for products and services depending on the cardholder's accumulated debt (i.e., promise to the card issuer to pay them for the amount plus the more agreed charges).

The card issuer (often a bank or credit union) establishes a revolving account and provides the cardholder with a line of credit, which they can use to obtain a cash advance or to make payments to merchants. Consumer and commercial credit cards are the two types of credit cards available. Most cards are made of plastic, but others are made of metal (stainless steel, gold, palladium, titanium), and a few are made of metal that has been covered in gemstones.

Hence, option (A) is accurate.
