Introduction to Probability, 2
A motorist goes through 4 lights, each of which is found to be red with probability 1/2 . The waiting times at each light are modeled as independent normal random variables with mean 1 minute and standard deviation 1/2 minute. Let X be the total waiting time at the red lights. (a) Use the total proba
