In a group of 200 high school students, 36 are taking biology, 52 are taking Spanish, and 126 are taking neither biology nor Spanish. If one of these 200 students is to be chosen at random, what is the probability that the student chosen is taking biology but not Spanish?

1 answer

If x are taking both biology and Spanish, then

36+52-x = 200-126
x = 14

So, 36-14=22 are taking biology but not Spanish.

That should get you started.
