Hint for Section 6.3 Question 3

3. Let S represent the students who study statistics, C represent the students who study calculus, and L represent the students who study logic.
We must find n(S � C � L). We know that

n(S � C � L) = n(S) + n(C) + n(L) - n(S � C) - n(S � L) - n(C � L) + n(S � C � L).

Now substitute the information given in the problem into the above equation to find n(S � C � L).
