What is 14 choose 7?

Answer

14 choose 7 is
3,432

Order doesn't matter, no repeats: 3,432 ways to choose 7 of 14 items.

C(14, 7) = 14! / (7! · 7!)

= (14 × 13 × 12 × … × 8) / (7 × 6 × 5 × … × 1)

7 factors on top and bottom

= 17,297,280 / 5,040

= 3,432

If order matters (permutations): P(14, 7) = 14 × 13 × 12 × … × 8 = 17,297,280 — each combination in 7! = 5,040 orders.

What is 14 choose 7?

14 choose 7 is 3,432

Why is 14 choose 7 the largest number in row 14?

In row 14 of Pascal's triangle the numbers grow towards the middle and shrink after it, because n choose k = n choose (n − k). With an even n the middle is k = 7, so 14 choose 7 = 3,432 is the largest: 14 choose 6 is only 3,003.

How many ways are there if order matters?

P(14, 7) = 17,297,280. Each of the 3,432 combinations can be put in order in 7! = 5,040 ways, so permutations = combinations × k!: P(n, k) = n! / (n − k)!.
