**MathMate**, Friday, March 23, 2012 at 12:31amDraw a Venn diagram or use the inclusion/exclusion principle to show that

there are 70-30=40 students passed only math, and 56-30=26 students passed only statistics.

So there is a total of 40+26=66 students who passed only one subject.

So what is the probability of randomly choosing one student from a class of 125 such that this student is one of 66 who passed only one subject?
