Alexis calculated right, the answer is 60 (5*4*3=60) but it can also be different since it did not say there will be no repetitions, we can choose out of the 5 given numbers: 1,3,5,7,9 and there was already a hint in the word problem which is 'three digit numbers' so to make it easy, 5*5*5= 125
But if you use the NCr calculation to get the possible samples then you'll get= 10
N!/(N-n)!n! - > 5!/(5-3)!3!
I wonder what happens if they answer this instead, will it be wrong or not
