Document Summary
Legibly, please: if you have a question, ask it, use the back sides of the test sheets for rough work or extra space, you may use a calculator and an aid sheet, do any two (2) of a c. [10 = 2 5 each: a fair coin is tossed ve times. What is the probability that at least four tails will come up: compute p (x 1) if the random variable x has the probability density function f (x) = (cid:26) 1. 0 x < 1 or x > 1: suppose that a and b are events in some sample space, with p (a) = p (b) = 1. What is p (a b): do any two (2) of a c. [10 = 2 5 each: a fair coin is tossed, and then tossed some more until it comes up with the face other than the one that came up on the rst toss.
