What is 25P3?

Answer 1

25P3 represents the number of permutations of 25 items taken 3 at a time. It is 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. For 25P3, this would be ( \frac{25!}{(25-3)!} = \frac{25!}{22!} = 25 \times 24 \times 23 = 13,800 ). Thus, 25P3 equals 13,800.
