There are 6! ways = 720 ways: PROOF:


1st guy has 6 ways
2nd guy has 5 remaining ways
3rd guy has 4 remaining ways
4rth guy has 3 remaining ways
5th guy has 2 remaining ways
6th guy has 1 remaining way
So in total there are 6x5x4x3x2x1 = 750 ways

you have to multiply 6*5*4*3*2*1 so it will be 720
