Suppose there are four traffic lights on the way from your home to campus. It is assumed that when you encounter a red signal, you must stop 50s, 50s, 30s and 20s for the first, second, third, and fourth light, respectively. In addition, the probabilities of encountering a red signal and green signal (no waiting time) are both 0.5. (a) Determine the sample space of the waiting time due to the four traffic lights. (b) Compute the probabilities of all possible outcomes in (a). Suppose there are four traffic lights on the way from your home to campus.
