Answer #1
Four possibilities for the first number.

Four possibilities for the second number

Therefore, 4x4 = 16 possibilities for the first two numbers.

Four possibilities for the third number

Therefore, 16x4 = 64 possibilitites for the first three numbers.

I think you can now see what the total number of arrangements of all four numbers will be.
