Conditional Probability Formula

In an experiment, the probability that event A occurs is 2/5, the probability that event B occurs is 1/3, and the probability that events A and B both occur is 1/7.

What is the probability that A occurs given that B occurs?

(a)  

In an experiment, the probability that event A occurs is 1/6, the probability that event B occurs is 2/9, and the probability that events A and B both occur is 1/8.
