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:-

$C(m,n)=\frac{m!}{n!(m-n)!}$

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

$C(5, 2)=\frac{5!}{2!(5-2)!}=\frac{5\times4\times3!}{2\times3!}=10$

Hence, C(5, 2)= 10
