You can solve this problem by doing the equation for combinations: which in this case is 4x3x2x1. So the answer is 12 different ways. no actually the answer is 24 different ways because 4x3x2x1=24 same as 4!
Mathematically speaking, if you line them up in one straight line, there are 5040 ways. You do 7*6*5*4*3*2*1=5040. The * means multiply.
There are n! (n factorial) ways that n people can stand in line. So six people can stand in line in: 1*2*3*4*5*6 = 720 different ways
If the people are always facing forward? 24 ways.

To arrange a family of five in one line for a photo, you can use the concept of permutations. The number of ways to arrange five people is calculated as 5! (5 factorial), which equals 5 × 4 × 3 × 2 × 1 = 120. Therefore, there are 120 different ways to arrange a family of five in a line.
