Indicate the formula for the following conditions.

c(n, r) =

i got c(n, r) = ( n r. ) = n! r! (n−r)! so far but i'm not sure what to do after this

nCr = n! / (r!(n-r)!),

Step-by-step explanation:

The formula for C(n,r), also known as "n choose r" or a combination,

is: 

nCr = n! / (r!(n-r)!),

where n is the total number of options and r is number you must choose

The number generated is the total number of possible combinations. 

The ! means factorial. For example, 4! = 4 x 3 x 2 x 1

the answer is c just got it on ed

step-by-step explanation:

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
