What is a grouping of objects or events in which order does not matter?

The grouping of a subset of a set of items where the order does not matter is called a combination. One such example is the UK's National Lotto where 6 numbers have to be chosen from the 59 numbers 1-59).If there are n different items and a subset of r of them are chosen where the order of choosing does not matter then the number of combinations is given by:nCr = n!/((n-r)!r!)where n! means "n factorial" - the product of all numbers 1 × 2 × ... × n; 0! is defined to be 1.--------------------------------------------------------------------------------------------------------------------------------Where the order of selection does matter, it is called a permutation. One such example would be the order of the first three runners in a race.If there are n different items and a subset of r of them are chosen where the order of choosing does matter, then the number of permutations is given by:nPr = n!/(n-r)!

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.
