The probability that event A occurs is .79. The probability that event B occurs is .58. The probability that both events A and B occur is .26, find P(B\A).

I think P(B\A) means the probability that B happens but A does not. This is different than P(B|A), the probability that B happens given that A has happened.
P(B\A) = P(B) - P(AB) = .58 - .26 = .32

Well according to me, if we use the formula
P(b/a) = P(a and b) / P(a) the answer comes out to be .329
Please let me know if i am right or not

P(B|A) = P(AB)/P(A) = 0.26/0.79 = 0.329
