Part 1. A fair coin is flipped and it is noted whether heads or tails show. A fair20-sided die is tossed and the number on the bottom face is noted. What is the probability of the event "tailsshows on the coin and an even number on the die"?

Part 2. Two fair tetrahedrons (4 sided), each with equal sides numbered from 1 to 4, are identical except that one is red and the other white. If the two tetrahedrons are tossed and the number on the bottom face of each is observed, what is the probability of the event "the sum of the numbers is6"?
