Question 917124: There are 50 students in a class. 24 of them took algebra, 32 of them took biology, and 2 of them took neither courses. How many students took both courses? Answer by ewatrrr(24785) (Show Source):
You can put this solution on YOUR website! 24 + 32 = 56
50-2 = 48 took either one or both
56 - 48 = 8 took both courses
and... checking
16 + 24 + 8 = 48
