A university offers 3 calculus classes: Math 2A, 2B, and 2C. A set of students have each taken at least one of the three classes
lyudmila [28]

Answer:

157

Step-by-step explanation:

We are given that

Number of students in maths 2A=n(2A)=51

Number of students in math 2B=n(2B)=80

Number of students in math 2C=n(2C)=70

Number of students in maths 2A and 2B=n(A\cap B)=15

Number of students in maths 2B and 2C=n(B\cap C)=13

Number of students in maths 2A and 2C=n(A\cap C)=20

Number of students in maths 2A ,2B and 2C=4

We have to find the number of students in a set.

Formula:n(A\cup B\cup C)=n(A)+n(B)+n(C)-n(A\cap B)-n(B\cap C)-n(A\cap C)+n(A\cap B\cap C)

Substitute the values in the given formula

n(2A\cup 2B\cup 2C)=51+80+70-15-13-20+4=157

Hence, total number of students in a set=157
