Step-by-step explanation:
Combinations are a way to calculate the total outcomes of an event where order of the outcomes does not matter.
Formula to calculate combination
nCr = n! / r! * (n - r) !
We are given C (7,3)
here n = 7
r = 3
So plug values in the formula
7C3 = 7! / 3! * (7 - 3) !
= (7x6x5x4x3x2) / (3x2) (4x3x2)
= (7x6x5) / (3x2)
= 210 / 6
= 35
