Here is the question:
I have posted a link there to this topic so the OP can see my work.Very difficult precalculus quantitative methods questions, please help!?
Of 150 students registered at a local university, 76 are attending an accounting course, 49 are taking statistics, 55 in economics, 24 attending the accounting and the statistics course, 22 registered in both statistics and economics courses and 15 are taking all three courses. (A Venn diagram may prove useful)
1) how many students are taking both the statistics and the economics courses without taking the accounting course?
2) how many students are attending the statistics course but nether the accounting nor the economics courses?
3) how many students are taking the accounting course or the statistics course or the economics course?
4) how many of these 150 registered students are not taking any of these three courses?
