Your job is to guess the 3-digit access code, and each number can be used only once in the 3-digit sequence.
However, the order does matter! So, while 1, 22, 18 would work - 1, 18, 22 would not.
Catch my drift?
Now, I'm wondering, first, how many possible combinations there are taking the order of the numbers as a factor.
Second, say the order didn't matter and you could put 1 2 3 or 3 1 2 and both would work - how many possible combinations are there now.
Thanks in advance for help guys!
