1. Combinations with RepetitionActually, these are the hardest to explain, so we will come back to this later.2. Combinations without RepetitionThis is how lotteries work. The numbers are drawn one at a time, and if we have the lucky numbers (no matter what order) we win!

Permutations and combinations, the various ways in which objects from a set may be selected, generally without replacement, to form subsets. This selection of subsets is called a permutation when the order of selection is a factor, a combination when ord
Permutations and Combinations:In mathematics, permutations and combinations are both groups of elements. However, permutations are different orderings of a given group, so order matters in permutations, whereas combinations are groups of elements in which order does not make a difference. We have a ...
Permutations have an ordering and use all the elements from a set, while combinations don’t have an ordering and use any number of elements from a set. To get a better idea of these terms, Table 6-1 shows the difference between permutations and combinations, with and without repetition, ...
The upper factorial is the upper index, and the lower factorial is the difference of the indices. When the 6!'s cancel, the fraction reduces to 10·9·8·7.This is the number of permutations of 10 different things taken 4 at a time....
Combinations and Permutations on the GRE The rule of thumb is that combinations are unordered and permutations are ordered, but what does that mean? We like illustrating the difference using a social club. Imagine the social club has 10 different members and you’re asked, “How many groups of...
How to do permutations and combinations in word problems What is the formula for a permutation? How to find the order of a permutation How many distinguishable permutations are in the word "initial." In mathematics, what is the difference between permutation and combination?
Permutations vs combinations The difference between combinations and permutations is that permutations have stricter requirements - the order of the elements matters, thus for the same number of things to be selected from a set, the number of possible permutations is always greater than or equal to...
