The number of ways in which 5 persons can stand in a row for a photograph is determined by the number of permutations of 5 distinct items, which is given by the formula P(n) = n!.

Here's the step-by-step calculation:

1. Start with the number of people, which is 5.
2. Calculate the factorial of this number. The factorial of a number is the product of all positive integers less than or equal to that number.

So, 5! = 5 * 4 * 3 * 2 * 1 = 120.

Therefore, 5 people can stand in a row for a photograph in 120 different ways.
