Am I on the right track:
44*43*42*41*40=40,320,960 possible combinations
That's 130320960
How do I find the probability?
--------------------
That's the start, but because the order doesn't matter, there are 5 chances for the 1st number to be selected, 4 chances for the 2nd, etc, so you divide by
5*4*3*2*1, or 5!
= 44*43*42*41*41/120 = 130320960/120 = 1 chance out of 1086008
