1) (5 points) If Mark McGwire has hit a home run in 50 of his last 400 plate appearances and we assume he will continue to hit home runs at the same rate, what is the probability he will hit no home runs in three plate appearances.
2) (5 points) Say we have five events (A, B, C, D, E) with
the following probabilities. Which events are impossible? Of those
possible rank them in order from least likely to most likely.
P(A) = 0.01; P(B) = -0.05; P(C) = 1.20; P(D) = 0.99; P(E) = 1.00
3) (5 points) If you guess at every question on a ten-question true-false exam, what is the probability you will get eight out of ten answers correct?
