Suppose 52 of the students in class have a calculator and 14 have a computer. It is known that 4 do not have either a computer or calc and there are 64 students in the class. Find the probability that a randomly chosen student has a computer AND a calculator.

I know this is an intersection, but don't know how to find the answer. I tried to set up a table, but i have no idea if that would work.
