Answer

The factorial, written as n!, is the product of all positive integer values of n, from 1 to n. For this problem, n=9, therefore the factorial is 9!=9×8×7×6×5×4×3×2×1

Steps

Step 1 ：To determine the number of ways 9 people can line up for a picture, we need to calculate the total number of permutations.

Step 2 ：A permutation is an arrangement of objects in a specific order. In this case, there are 9 people, so the number of permutations can be calculated as the factorial of 9.

Step 3 ：The factorial, written as n!, is the product of all positive integer values of n, from 1 to n. For this problem, n=9, therefore the factorial is 9!=9×8×7×6×5×4×3×2×1
