Solution

To evaluate the expression C52 we use the following formula

nCr =n!/r! (n – r)!

n = 5

r = 2

Substitute n and r values in above formula

nCr =n!/r! (n – r)!

C52= 5!/2! (5-2)!

C52= 5!/2! (3)!

Find the factorial for 5!, 2! & 3!, substitute the corresponding values in the below expression and simplify.

= 5 × 4 × 3 × 2 × 1/(2 × 1)( 3 × 2 × 1)

= 120/(2 )(6)

= 120/12

= 105C2= 10

Answer

C52= 10
