    Workout :
    step 1 Address the formula, input parameters & values
    n = 10
    k = 4
    Find what is 10 CHOOSE 4?

    step 2 Substitute n and r values in below nCk formula

    nCk = n!/k! (n - k)!
    10 CHOOSE 4 =10!/4! (10 - 4)!

    step 3 Find the factorial for 10!, 4! & 6!, substitute the corresponding values in the below expression and simplify.

    10C4 = 10!/4! (6)!

    =1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 x 9 x 10/(1 x 2 x 3 x 4) (1 x 2 x 3 x 4 x 5 x 6)

    = 7 x 8 x 9 x 10/24
    = 5040/24

    10C4 = 210
