Question 1157328
In how many ways can a baseball team of 9 players be formed from a group of 18
players. If only 3 can be catchers, only 6 can be pitchers, and the rest can
only take one of the other positions?
<pre>
Can the 3 that can be catchers play another position besides catcher, or can they ONLY be the catcher and nothing else?

Can the 6 that can be pitchers play another position besides pitcher, or can they ONLY be the pitcher and nothing else?

The answer to those questions cannot be determined from the wording above.  But
I will assume the answer is "yes":  

Choose the catcher 3 ways.
Choose the pitcher 6 ways.
Choose the other 7 positions from the remaining unchosen 16 players in 
3∙6∙16P7 = 3∙6∙16∙15∙14∙13∙12∙11∙10 = 1,037,836,800 ways.
