there are 324 students in a college who have taken a course in calculus, 211 who have take a course in discrete mathematics, and 135 who have taken a course in both calculus and discrete mathematics. how many students at this college have taken a course in either calculus or discrete mathematics?



Answer :

265 students at this college have taken a course in either calculus or discrete mathematics.

Let X = number of students who have taken a course in calculus

Y = number of students who have taken a course in discrete mathematics

To determine the number of students who have taken a course in calculus only, subtract 135 from 324.

Only X = X - X∩Y

Only X = 324 - 135

Only X = 189

To determine the number of students who have taken a course in discrete mathematics only, subtract 135 from 211.

Only Y = Y - X∩Y

Only Y = 211 - 135

Only Y = 76

To determine the number of students who have taken a course in either calculus or discrete mathematics, add 189 and 76.

either X or Y = only X + only Y

either X or Y = 189 + 76

either X or Y = 265

To better illustrate the X and Y, see the attached photo of the Venn Diagram.
