What is the ratio of the number of permutations of 14 items taken six at a time to the number of combinations of 14 items taken six at a time?

Question

What is the ratio of the number of permutations of 14 items taken six at a time to the number of combinations of 14 items taken six at a time?

Answer 1

₁₄P₆ = 14!/(14-6)!

₁₄C₆ = 14!/{(6!)(14-6)!}

So, ₁₄P₆/₁₄C₆ = 6!
