Hello. What have you thought about or tried, so far?

Did you organize the given information? For example, you could write numbers of players inside a two by two grid.

Label the left column Female; label the right column Male.

Label the top row Blond; label the bottom row Not Blond.

You're told that 3 players are blond females. Write 3 in the spot for blond females (upper left).

Can you reason out the number of players in the other three spots? :cool:

PS: Be sure to read the forum guidelines.

I've sorted it into a venn diagram. There are 9 girls, 12 blondes, and 3 of both. I'm confused about where to go from there, I'm tossing up between 15 and 21.

What does your Venn diagram look like?

There are 9 girls, 12 blondes, and 3 of both.
Wait! That's not what you wrote in your first post.

You said there are 15 girls, 12 blondes, and 3 of both.

How are you arriving at two different values from your diagram? You set up the universe and the two circles:

Code:
Venn diagram:

*----------------------------*
|                            |
|  blonde: 12     female:15  |
|     ------    ------       |
|   /        \/        \     |
|  /         /\         \    |
| |         |  |         |   |
| |         |  |         |   |
| |         |  |         |   |
|  \         \/         /    |
|   \        /\        /     |
|     ------    ------       |
|                            |
*----------------------------*
universe: 24
And then what?
