84. If the P(A) = 0.20 and P(B) = 0.30 and the two events are mutually exclusive, what is the P(A B)? zero Difficulty: Easy Type: Concept 85. If the P(A) = 0.20 and P(B) = 0.30 and A and B are known to be independent, what is the probability of the intersection of A and B? 0.20 x 0.30 = 0.06, if A and B are independent Difficulty: Medium Type: Computation 86. Ten people try out for a local basketball team. If only five people can be chosen for the team and all players can play all positions, how many ways can this team be chosen? combination of 10 choose 5 = 252 Difficulty: Medium Type: Computation 87. Suppose 100 people enter a drawing for three grand prizes of $10,000, $5,000 and $1,000. How many ways can the winners for these three prizes be selected? permutation of 100 choose 3 = 100 x 99 x 98 = 970,200 Difficulty: Medium Type: Computation 88. If the probability of event A is 0.82, what is the probability of the complement of event A? 1 - 0.82 = 0.18 Difficulty: Easy Type: Computation
