Events A and B are dependent events. The probability that event A occurs is 20%. The probability that events A and B both occur is 8%. What is the probability that event B occurs given that event A occurs? Explain how you found your answer.

Answer 1

This is conditional probability

Prob(B given A)
= P(B | A)
= P( A and B)/P(A)
= .08/.2
= .....
