we can say combination is (5 & 3) can be like this ( 5.4.3 )/3!=10 its like the same for permutation p(5,3) = 5.4.3=60 you go down from 5 3 times;)

Another thing that causes confusion is the phrase "locker combination". In math we are told that when we are finding combinations, that order does not matter, but when we need to open a lock, the order of the numbers matter, but it is still called a "locker combination". It should be called a locker Permutation because the order of numbers obviously matters.
