P(x y) conditional probability

P(x y) conditional probability-\( 70xy = 1\) which gives \( x y = 50 \) Let event S product selected is a software product , let event H product selected is a hardware product Let event A product selected is from company A , let event B product selected is from company B We are asked to find the conditional probability \( P(HB) \)And what's so cool about conditional probability is that it's not limited to sample spaces with equally likely outcomes In other words, this means that the probability of observing events B and A is the probability of observing A, multiplied by the probability of observing B, given that you have observed A
