The 150 residents of the town of wonderland were asked their age and whether they preferred vanilla, chocolate, or swirled frozen yogurt. the results are displayed next. chocolate vanilla swirl under 25 years old 40 20 15 at least 25 years old 15 40 20 what is the probability that a randomly selected customer prefers vanilla?

Residents who are under 25 years and those above are mutually exclusive. Let V = number of persons who take Vanilla under 25yrs and V' be the number of residents who are at least 25yrs who take Vanilla. Okay, so P(V) = 40/150 and P(V') = 15/150 P(V or V') = 40/150 + 15/150 = 0.366

thats a lot
