Hi Awolfe,

To find the possible combination for 3 digit numbers, use the formula C ( n, r) where n is equal to 3! (or  3 x 2 x 1) and r is 1! (1X 1).  3 x 2 x 1 yields 6 so you will have total of 6 possible combinations using 3 digit numbers.

The combinations are:  345, 354, 435, 453, 534, 543

Hope this helps!
