Question 704507
There are 12 ways to choose the first kid


There are 12-1 = 11 ways to choose the next kid (assuming the first kid can't be placed back in the mix and potentially chosen again)


There are 12-2 = 10 ways to choose the third kid.


So there are 12*11*10 = 1320 different ways to choose 3 kids where order matters.


If order does not matter, then you'll have to divide by 6 because there are 3! = 6 ways to arrange any particular group. So if order does not matter, then there are 1320/6 = 220 different ways.


Summary:


If order does matter, then there are 1320 different ways


If order does NOT matter, then there are 220 different ways
