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?

    74 are taking something
    36+52 = 88, so 14 are taking both.
    So, 22 are taking biology only

    22/200 = .11 is P(biology only)
