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?

Total # of students = 200
Biology students = 36
Spanish students = 52
Other students = 126
36+52+126 does not even = 200 students total

200 (total students)
178 (total it can't be chosen)
____
22
22/200 = 11/100 = 11%
This is not the only way to solve it.
