SOLUTION: It is not clear to me how to solve (nx) = n! / x!(n-x)! Such as if I have n as 15 and P = .01 is it 15! / .01! (15-1)! thus 1307674368000/ .01 (87178291200 =1307674

Question 505701: It is not clear to me how to solve
(nx) = n! / x!(n-x)!
Such as if I have n as 15 and P = .01
is
it 15! / .01! (15-1)!
thus
1307674368000/ .01 (87178291200
=1307674368000/ .01 (87178291200)
=1307674368000/ 871782912
= 1500
This seems incorrect when dealing with a sample size of 15 and a 1% will have a side effect

You can put this solution on YOUR website!
Your formula is the number of ways to choose x objects from a set of n, so you cannot have numbers there that aren't integers.
