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:
In which a is the number of students who have taken a course in calculus but not in discrete mathematics and is the number of students who have taken a course in both calculus and discrete mathematics.
By the same logic, we have that:
188 who have taken courses in both calculus and discrete mathematics.
This means that
212 who have taken a course in discrete mathematics
This means that
345 students at a college who have taken a course in calculus
This means that
How many students have taken a course in either calculus or discrete mathematics
369 students have taken a course in either calculus or discrete mathematics
