On your drive to school, you encounter two intersections with traffic signals. There is a probability 0.6 that you will have to stop at the first light, a probability 0.3 that you will have to stop at the second light, and a probability 0.1 that you will have to stop at both lights. Let A = stop at first light and B = stop at second light. Calculate the following. (a) P(A or B) = (b) P(A and BC) = (C) P(stop at exactly one signal) =
