Three people are selected at random.20 (a) What is the probability that the first person is male and right-handed? (b) What is the probability that the first two people are male and right-handed?. (c) What is the probability that the third person is female and left-handed? (d) What is the probability that the first two people are male and right-handed and the third person is female and left-handed? Sometimes we wonder if one outcome provides useful information about another outcome. The question we are asking is, are the occurrences of the two events independent? We say that two events A and B are independent if they satisfy P(A and B) = P(A) × P(B).
