## How to Find 3C2 or 3 CHOOSE 2?

The below is the complete work with step by step calculation for 3 CHOOSE 2 may helpful for grade school students to learn how find all possible combinations of 3C2 for sample space S in the statistical experiment or to solve the combinations worksheet problems by just changing the corresponding input values of 3 CHOOSE 2 calculator.

Workout :
step 1 Address the formula, input parameters & values
n = 3
k = 2
Find what is 3 CHOOSE 2?

step 2 Substitute n and r values in below nCk formula

nCk = n!/k! (n - k)!
3 CHOOSE 2 =3!/2! (3 - 2)!

step 3 Find the factorial for 3!, 2! & 1!, substitute the corresponding values in the below expression and simplify.

3C2 = 3!/2! (1)!

=1 x 2 x 3/(1 x 2) (1)

= 3/1
= 3/1

3C2 = 3
