Number of people choose either calculus or discrete math is 369

Given that;

Number of people choose calculus = 345

Number of people choose discrete math = 212

Number of people choose Calculus and discrete math = 188

Find:

Number of people choose either calculus or discrete math

Computation:

Number of people choose either calculus or discrete math = Number of people choose calculus + Number of people choose discrete math - Number of people choose Calculus and discrete math

Number of people choose either calculus or discrete math = 345 + 212 - 188

Number of people choose either calculus or discrete math = 369

369 students have taken a course in either calculus or discrete mathematics

Step-by-step explanation:

I am going to build the Venn's diagram of these values.

I am going to say that:

A is the number of students who have taken a course in calculus.

B is the number of students who have taken a course in discrete mathematics.

We have that:

$A = a + (A \cap B)$

In which a is the number of students who have taken a course in calculus but not in discrete mathematics and $A \cap B$ is the number of students who have taken a course in both calculus and discrete mathematics.

By the same logic, we have that:

$B = b + (A \cap B)$

188 who have taken courses in both calculus and discrete mathematics.

This means that $A \cap B = 188$

212 who have taken a course in discrete mathematics

This means that B = 212

345 students at a college who have taken a course in calculus

This means that A = 345

How many students have taken a course in either calculus or discrete mathematics

$(A \cup B) = A + B - (A \cap B) = 345 + 212 - 188 = 369$

369 students have taken a course in either calculus or discrete mathematics
