How do you find the permutation or combination of 7C4?

We can find the permutation or combination of 7C4 using the nCr = n!/r!(n – r)! formula.

Answer: The permutation or combination of 7C4 is 35

Let us see how we can find the permutation and combination of 7C4.

Explanation:

7C4 = 7! / 4!(7 – 4)!

= 7! / (4! 3!)

= (7 × 6 × 5 × 4!) / (4! 3!)

= (7 × 6 × 5) / (3 × 2 × 1)

= 7 × 5

= 35

Thus, the permutation or combination of 7C4 is 35.
