How many ways can you arrange a people in a row?

The number of ways to arrange ( n ) people in a row is given by ( n! ) (n factorial), which is the product of all positive integers up to ( n ). For example, if you have 3 people, the arrangements would be ( 3! = 3 \times 2 \times 1 = 6 ) ways. Thus, to find the number of arrangements for any given number of people, simply calculate the factorial of that number.
