Here's another problem that I am having trouble with....

An exit poll yeilded the following information concerning peoples voting patterns on Propositions A, B, and C.

795 voted yes on A
816 voted yes on B
612 voted yes on C
39 voted yes on all three (union of A,B, and C)
103 voted no on all three (complement)

380 voted yes on B and C
1472 voted yes on A or B
450 voted yes on A only

The question is:
What is the probability that a voter voted yes on more than one proposition?

I put my notes in brackets for what I understand, however I get confused when it comes to the rest of the problem...PLEASE HELP!
 
I will help you start the Venn diagram.
