Question

Evaluate C(5, 2).

10
20
60

Answer 1

(5 * 4)/(2 * 1) = 20/2 = 10 or A

Answer 2

Answer: 10

Step-by-step explanation:

• C(m,n) are used to denote a binomial coefficient. It is the number of ways of selecting n outcomes from n possibilities without being in order or sequence.

The value of the binomial coefficient for non-negative m and n is given by:-

`C(m,n)=(m!)/(n!(m-n)!)`

Therefore, the value of C(5, 2) is given by :-

`C(5, 2)=(5!)/(2!(5-2)!)=(5*4*3!)/(2*3!)=10`

Hence, C(5, 2)= 10
