Question 1115286: At a college, 55% of the students pass Math, 70% pass Biology, and 25% pass both of these courses. If a student is selected at random, Find the probability that a student passes Math given that he passed Biology. Answer by ikleyn(52780) (Show Source):
In order for to make the situation maximally obvious/visible/tangible, imagine the equivalent formulation.
There are 100 students; 55 of them passed Math; 70 passed Biology, and 25 passed both.
Find the ratio of those who passed Math given that they passed Biology.
I do not need explain to you that this ratio is - it is self-evidently.
Answer. The probability under the question is = = 35.71%
