A professor gave his 40 students a test with three questions. Every student answered at least one question. Ten student did not answer the first question, 14 did not answer the second question, and 12 did not answer the third question. If 18 students answered all three questions, how many answered exactly one question?

Lots of our students are helped by other students. You are welcome to help answer questions any time you are sure of the answer. But also remember, it helps students to know HOW to find the answers so they'll know how to the same type of problem next time.
