In a survey of 240 television viewers, 3/5 indicated that they like comedies, some indicated that they do not like comedies, and the rest did not respond. If one of the 240 viewers is selected at random, the probability is 1/15 that the viewer selected did not respond. How many of the 240 viewers indicated that they do not like comedies?

Answer 1

liked: 3/5 * 240 = 144
no response: 1/15 * 240 = 16
So, 240-144-16 = 80 did not like comedies
