A professor knows that in her class 37% of the students have passed an Algebra course, 29% have passed an English course, and 21% have passed both courses. If one student is selected at random from this class, find the probability that:

math  MathMate, Sunday, April 24, 2011 at 3:09pm
37% passed algebra,
21% passed both, so
(3721)=16% passed only algebra.
Similarly,
(2921)=8% passed only English.
With these numbers, you should have no difficulties calculating the probabilities that you forgot to post.
