Assuming all 9 numbers are one digit and different
1st number can be any of the 9 numbers
2nd any of the remaining 8 numbers
3rd any of the remaining 7 numbers
4th any of the remaining 6 numbers
5th any of the remaining 5 numbers
So total is 9 x 8 x 7 x 6 x 5 = 15,120 combinations
* * * * *
That is the number of permutations, not combinations.
In the above method, 12345, 12354, 12435, etc would all be counted as different even though they are all the SAMEcombination of numbers. Thus there are 120
The correct answer is 9C5 = 9*8*7*6*5/(5*4*3*2*1) = 126 combinations.
