Question: 1. A die is tossed that yields an even number with twice the probability of yielding an odd number. What is the probability of obtaining an even number, an odd number, a number that is even or odd, a number that is even and odd?
2. If a single letter is selected at random from {A, B, C}, find the probability of all events. Recall that the total number of events is 2 N, where N is the number of simple events. Do these probabilities sum to one? If not, why not?
