Explanation

To solve the problem of arranging 6 boys and 5 girls for a group photograph, where the girls sit on chairs in a row and the boys stand behind them, we can follow these steps:

### Step 1: Arrange the Girls
The first step is to arrange the 5 girls in the chairs. Since the girls are distinct individuals, the number of ways to arrange them is given by the factorial of the number of girls.

\[ \text{Number of ways to arrange 5 girls} = 5! = 5 \times 4 \times 3 \times 2 \times 1 = 120 \]
