Question

A and B are independent events. Use the following probabilities to answer the question. Round to 4 decimal places. P(A)=0.25,P(A and B)=0.12, find P(B) P(B)=________

Answer 1

Answer:0.48.

Explanation:

P(B) = P(A and B) / P(A)

Given that P(A) = 0.25 and P(A and B) = 0.12, we can substitute these values into the formula:

P(B) = 0.12 / 0.25

To simplify the calculation, we divide 0.12 by 0.25:

P(B) = 0.48

Therefore, the probability of event B, P(B), is 0.48.
