## How to Find 4C4 or 4 CHOOSE 4?

The below is the complete work with step by step calculation for 4 CHOOSE 4 may helpful for grade school students to learn how find all possible combinations of 4C4 for sample space S in the statistical experiment or to solve the combinations worksheet problems by just changing the corresponding input values of this 4 CHOOSE 4 calculator.

Workout :
step 1 Address the formula, input parameters & values
n = 4
k = 4
Find what is 4 CHOOSE 4?

step 2 Substitute n and r values in below nCk formula

nCk = n!/k! (n - k)!
4 CHOOSE 4 =4!/4! (4 - 4)!

step 3 Find the factorial for 4!, 4! & 0!, substitute the corresponding values in the below expression and simplify.

4C4 = 4!/4! (0)!

=1 x 2 x 3 x 4/(1 x 2 x 3 x 4) (1)

= 1/1
= 1/1

4C4 = 1
