This is just the combination formula (nCr) found in a statistics book:
27!/5!(27-5)! ! stands for factorial .
so 27! = 10888869450418352160768000000
and 5!=120
and 22!=1124000727777607680000
ans=80730
note you would hardly ever write the factorial answers out, instead just hit the n! button on your calculator to get a factorial of a number i.e to get 27! just type 27 then n!.
