On vacations, Ann travels either to North or to South from her home. Each time, to choose where to go, she rolls a die. If the die shows one or two, Ann travels to North. If the die shows a number greater than two, she travels to South. Suppose that the probability that there will be rainy on vacation in North is 3/4, while for South the same probability is 1/4. a) Find the probability that it will be rainy on vacation. (Hint: you should graph a tree.) 3/ 12 5 / 12 0 7/ 12 1/3
