1. Assume three executions of a single if statement. At each execution the program takes either the then or the else branch (a) (5 points) List all possible outcomes. (b) (10 points) Assuming each outcome is equally likely, determine the probability of the following events: E "at least one then" E2 = "else on first execution" (c) (10 points) Now assume that the then execution is twice as likely and compute p(E) and p(E2)
