Question

In a survey of 240 television viewers, 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 that the viewer selected did not respond. How many of the 240 viewers indicated that they do not like comedies?

The correct answer is: 80

HINT: By subtracting the sum of those who liked comedies and those who didn't respond, from the total viewers gives the number of those who don't like comedies.
Complete step by step Solution
Given, there are 240 viewers.
Among these 240, $3 to the power of t h end exponent over 5$ liked comedies.
That is, $3 over 5 left parenthesis 240 right parenthesis equals 144$
So 144 viewers liked comedies.
Among theses 240, $1 over 15$ did not respond.
That is, $1 over 15 left parenthesis 240 right parenthesis equals 16$
So 16 viewers did not respond.
The remaining would be the viewers who do not like comedies.
That is, 240 - (144 + 16) = 80.
So, a total of 80 people do not like comedies.
