venn diagram (professional teams)

33 U.S. cities were surveyed

16 had baseball
17 had football
15 had basketball
11 had baseball and football
7 had baseball and basketball
9 had football and basketball
5 had all three teams

a) only a football team
b) baseball and football, but not basketball
c) baseball or football
d) baseball or football, but not basketball
e) exactly two teams

Were (a) through (e) perhaps prefaced with some sort of instructions...? Perhaps something along the lines of "use the above to find, for each of the following, the number of cities having the listed teams"...?

If your subject line refers to your post (and they frequently don't, so please forgive the assumption, if incorrect), then you need to start by deciding how many circles to draw, and how to label them.

What have you got so far? Please be specific. Thank you!

Assuming it is about Venn diagrams, how is this any different from this?

Except here we have three circles.

Now you show some work!
