Question

A survey is given to a class, asking about each person's favorite season of
the year. 15 people chose Winter, 35 people chose Spring, 10 people
chose Summer, and 40 people chose Fall. One person is chosen at
random from the class. What is the probability that that person's favorite
season is either Summer or Fall? *
