Answer 9

You'll use the combinations formula as the numbers do not have to be in a specific order. For each slot, 9 numbers could go there (slot 1 could have 1,2,3,4,5,6,7,8,or9... etc)
In your formula, n is the number of things you can choose from, and r is how many you choose. Then you can just substitute and solve =)

Answer 15

So what do you mean by examples 0 and 1?

Answer 16

For that they want me to put for 0,1,2,3,4,5,6,7,8,9
For 0 i put 9 and 1 i put 8 and 2 i put 7?

Answer 17

I don't quite understand, but from what I do get I don't think you're on the right track.
All you should need to do is figure out what 'n' and what 'r' is.

Answer 18

my heads about to blow from this question And Would N Be 3?

Answer 19

You know what, I am so sorry but I was wrong. Because each slot can only be occupied by one number, it is actually a permutation. Very sorry! So it is the same process, but the other formula.

To find N, how many numbers are available for you to choose from?

Answer 20

i can pick any number for 0-9 for n and r so all i gotta do is 10x9x8x7x6x5x4x3x2x1

Answer 21

which is B

Answer 22

I don't think it's B. You are correct that N is going to be 10, but then you have to also plug it into the formula.

Answer 23

C

Answer 24

3628800
