Hmmm I was thinking 5C2 which wld end up being 10 ... wait lemme just think abt this

OpenStudy (dan815):

yes 5*4

OpenStudy (mimi_x3):

But dan order doesnt matter in this sense

OpenStudy (dan815):

5 Choose 2 for be 2 equivalent spots like if they said how many ways to show 5 people for 2 vice presidents

OpenStudy (mimi_x3):

So its a combinationn not permutation

OpenStudy (dan815):

"order" matters as who is vicepresidents and president is different

OpenStudy (mimi_x3):
