-----------------------
Draw a rectangle.
Number of schools in the rectagle is 33.
--------------------
Draw three intersecting circles inside the rectangle
Label them baseball, football, basketball
Put a "5" in the intersection of all three circles
Put a "4" in the intersection of foot and basket since it already has a "5".
Put a "2" in the intersection of base and basket since it already has a "5"
Put a "6" in the intersection of base and foot since it already has a "5"
Continue this process as you fill in the rest of the three circles.

Count to find the answers to a,b,c...e
