Answer:
3,682,800 ways
Step-by-step explanation:
A permutation is the variation of the order or position of the elements of an ordered set.
Basically, if order doesn't matter, we talk about a combination. If order matters, it's about permutation.
In other words: A permutation is an orderly combination.
There are two types of permutations:
Repeat is allowed: as a lock combination, it could be "333".
Without repetition: for example the first three in a race. You cannot stay first and second at the same time.
In this case, factor notation is used, multiplying descending numbers.
10! = 10x9x8x7x6x5x4x3x2x1 = 3,682,800 ways
