If I have 10 #s 1-10 for EX and I can only choose 6 out of them what formula is there to find the possibilit?

Question

Example 1,2,3,4,5,6,7,8,9,10 and I can only choose six , how do I find the different possible outcomes?

Answer 1

I am assuming you mean choose a number and don't replace it, and also that you mean you want to put these numbers in order.

10*9*8*7*6*5 = 151200
