Question

In the application for admission to the master's degree of 350 students. 

Suppose that 220 of these applicants majored in computer science, 147 

majored in business, and 51 majored both in computer science and in business. 

How many of these applicants majored neither in computer science nor in 

business?

Answer 1

To find the number of these applicants who majored neither in computer science nor business we can subtract the number of students who majored cipher in computer science or in business or both) from the total number of applicants,

The number of students who majored either in computer science or in business (or both) is 220 + 147 - 51 = 316. Therefore, we conclude that 350 –316 = 34 of the applicants majored neither in computer science nor in business
