A researcher finds that, of 982 men who died in 2002, 221 died from some heart disease. Also, of the 982 men, 334 had at least one parent who had some heart disease. Of the latter 334 men, 111 died from some heart disease. A man is selected from the group of 982. Given that neither of his parents had some heart disease, find the conditional probability that this man died of some heart disease. Translation: Let A = {death by heart disease}, B = {at least one parent had some heart disease}. We have 221 P(A) = 982 334 P(B) = 982 111 P(ANB)= 982 What is P(A|B')? A small grocery store has 10 cartoons of milk, 1 of which is sour. If you are going to buy the sixth carton of milk sold at random, compute the probability of selecting a carton of sour milk.
