What is 15p3?

Answer 1

The notation (15P3) represents the number of permutations of 15 items taken 3 at a time. It can be calculated using the formula (nPr = \frac{n!}{(n-r)!}), where (n) is the total number of items and (r) is the number of items to choose. Thus, (15P3 = \frac{15!}{(15-3)!} = \frac{15!}{12!} = 15 \times 14 \times 13 = 2730). Therefore, (15P3) equals 2730.
