The combination formula is usually written as nCr representing the number of combinations of r objects at a time taken from n.
nCr = n!/[r!*(n-r)!]
The permutation formula is usually written as nPr representing the number of permutations of r objects at a time taken from n.
nPr = n!/r!
Where n! [n factorial] is 1*2*3*....*(n-1)*n

Why are combination locks so called when they are in fact permutation locks?
They are called combination locks because that is the general, conventional term used. Trying to call them permutation locks is mixing different areas of usage together and that is not valid.

What is the difference between permutation and combinations?
A permutation is an arrangement of objects in some specific order. Permutations are regarded as ordered elements. A selection in which order is not important is called a combination. Combinations are regarded as sets. For example, if there is a group of 3 different colored balls, then any group of 2 balls selected from it will be considered as a combination, whereas the different arrangements of every combination will be considered as a permutation.
When we use permutation or combination?
Permutation is when order matters, combination is when order does not matter
Permutation combination?
They are concepts used in probability theory.
Why are the answers from a permutation bigger than from a combination?
Because a permutation includes all the different arrangements or order of the items in a set. In a combination the order doesn't matter or count.
