Question

Required information Let S be the event that a randomly selected college student has taken a statistics course, and let C be the event that the same student has taken a chemistry course. Suppose P(S) = 0.32, P(C) = 0.27, and P(S ? C) = 0.17. Find the probability that a student has taken statistics but not chemistry. Round the answer to two decimal places.

Step 1

This can be found by subtracting the probability of the intersection of statistics and chemistry from the probability of statistics. P(Statistics but not Chemistry) = P(S) - P(S ∩ C) P(Statistics but not Chemistry) = 0.32 - 0.17 P(Statistics but not Chemistry) = Show more…
