In how many ways can center, power forward, small forward, point guard and shooting guard be selected in a set of 12 basketball players? ​

Sagot :

If position does not matter,

C(n,r)=C(12,5)  

=12!/(5!(12−5)!)

=12!/(5!×7!)

= 792 ways

If position matters,

P(n,r)=P(12,5)

=12!/(12−5)!

= 95040 ways
