Question 1112240: suppose that 75% of students taking calculus have previously had a trigonometry course. Of those that did, 75% pass their calculus class. Of those that did not, 40% pass calculus. What is the overall failure rate for calculus?

75%*75%=0.5625
25%*40%=0.10
The overall pass rate is the sum of 0.6625
The overall failure rate is 1-0.6625=0.3375
