Suppose each day that you drive to work a traffic light that you encounter is either green with probability 3/8, red with probability 1/2, or yellow with probability 1/8, independent of the status of the light on any other day. if over the course of five days, g, y, and r denote the number of times the light is found to be green, yellow, or red, respectively, what is the probability that p[g=2, y=1, r=2] ? also, what is the probability p[g=r]? [15%]. hint: consider sequences possible in a five-day observations
