3.1. (a) A random variable is a function that assigns a numerical value to each outcome in a sample space. (b) The expected value of a random variable is the long-run average value that the random variable takes on. 12) = P(Z &lt

5.2. (a) The z-score of X = 12 is z = (12 - 10) / 2 = 1. (b) The probability that X is less than 12 is P(X < 12) = P(Z < 1) = 0.8413. 1) = 0.8413.
