The answer is 0
The formula is
n!/ r!(n-r)!
4!/ 9!(4-9)!
I think it A... But if it not sorry I didn’t help... hope this is the answer I am sure it is...
First you would have to multiply everything by the parenthesis
5*2=10
5*5=25
So your equation should look like this
10*25*5
Then multiply from left to right
10*25=250
250*5=1250
So the simplified form of this is 1250
Hope this helps!
