Question 399035: how many ways can you arrange the numbers 0 through 9 picking 3 numbers at a time without repetition
Answer by ak21(6)   (Show Source):
You can put this solution on YOUR website! The answer is basically nPr, we use P as order is important here.
1) n= 10 ways (0-9)
2) r= 3,you pick 3 numbers out of the 10
you put, 9P3 in your calculator, which should get:
720 different ways.
OR: 10x9x8 (the number of ways, i am assuming you cant repeat).
Hope this helps.
