Answer to Problem 5LC
Number of people who use their cell phones to play only games are 26
Explanation of Solution
Given:
Total number of people are 80 in which 49 takes picture and 35 take picture as well as play games.
Let people who takes picture are represented by set A and people who play games are represented by set B,
Total number of people who takes picture or play games are,
Number of people who takes picture are,
Number of people who takes picture as well as play games are,
According to set theory,
Now, number of people who use their cell phones to play only games are,
