Question

Professor N. Timmy Date has 31 students in his Calculus class and 17 students in his Discrete Mathematics class.

(a) Assuming that there are no students who take both classes, how many students does Professor Date have?


(b) Assuming that there are five students who take both classes, how many students does Professor Date have?

Answer 1

Answer: a) 48

b) 43

Explanation:

Given : The number of students Professor Date has in his Calculus class = 31

The number of students Professor Date has in his Discrete Mathematics class = 17

(a) If we assume that there are no students who take both classes, then the total number of students Professor Date Has = 31+17=48

(b) If we assume that there are five students who take both classes, then the total number of students Professor Date Has = 31+17-5=43
