Answer: 80

Step-by-step explanation: The question is tell us that a certain company we don't know which one, but it says a certain company has 400 shoes. that is important to note. also 20% of the shoes are black. and One shoe is chosen and replaced. Then the second shoe is chosen. The question is What is the probability that the shoes chosen are black?

Well, take 400 and mutipy it by 20% which changes to 0.20 in decimal form then mutiply your answer by one and you get 80. so the answer is the probability that shoes chosen are black is 80%.

Answer: 4%

The probability of choosing a black shoe on the first draw is 20% or 0.2. Since the first shoe is replaced, the probability of choosing a black shoe on the second draw is also 20% or 0.2.

The probability of both events happening together is found by multiplying their probabilities. Therefore, the probability of choosing two black shoes in a row is:

0.2 x 0.2 = 0.04 or 4%

Therefore, the probability that the shoes chosen are black is 4%.
