WebThrough some browsing I've found that the number of combinations with replacement of n items taken k at a time can be expressed as ( ( n k)) [this "double" set of parentheses is the notation developed by Richard Stanley to convey the idea of combinations with replacement]. Alternatively, ( ( n k)) = ( n + k − 1 k). This is more familiar notation. WebFactorials. A factorial is represented by the sign (!). When we encounter n! (known. as ‘n factorial’) we say that a factorial is the product of all the whole numbers. between 1 and n, where n must always be positive. For example. 0! is a special case factorial. This is special because there are no positive numbers less than zero and we ...
