Evaluate C (7, 3). 4 35 70

option B

35

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
