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?

Dear Student, 
Solution) Total viewers = 240
​​Number of viewers like comedies = 3/5
Number of viewers that donot respond(donot like comdies)
= 1/15
Now, some donot like and rest did not respond 
=1-35+115=1-9+115=1-1015=15-1015=515=13
Therefore, number of viewers that donot like comedies 
=13×240=80Regards!
