Cher has forgotten the combination to her locker. She knows it consists of four numbers -- 3, 5, 7, and 9 -- but she can't recall the order. She decides to try every possible order until she gets the right one.
How many possible orders are there?

im pretty sure its 256. These r permutations right
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.
