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) =
0.35, P(C) = 0.25,
and P(S ∩ C) =
0.15.
Find the probability that a student has taken
statistics, chemistry, or both. Round the answer to two decimal
places.
