combination and the fundamental counting principle...

Hey everyone,

I was doing this problem and now I am second guessing myself.  Could you let me know if I'm right? I just want to make sure. Thank you in advance.

There are 8 women and 9 men trying out for a cheerleading squad.

The squad will consist of 6 people, only 2 men.

How many squads are possible?


First...

you find the possible combinations of 2 men from the 9 trying out:

Second...

you find the possible combinations of 4 women from the 8 trying out:

Third...

you multiply those possibilities together (by fundamental counting principle):

possible squads.

Am I missing anything?

Hi;


In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Hi 4DLiVing;

Glad to help and please do not call me sir, makes me feel old, bloated and unattractive.
