# Given a set X = { x 1 ,   x 1 ,   ​ … ,   x n } , an r-combination with repetition allowed. or a multiset of size r, chosen from X is , which is denoted .

To determine

To fill:

The blank in the given statement.

Explanation

Given information:

The given statement is,

“Given a set X={x1,x2,,xn}, an r -combination with repetition allowed, or a multiset of size r, chosen from X is _____, which is denoted _____”.

By definition, we know that:

An r-combination with repetition allowed, or multiset of sizer, chosen from a set X of n elements is an unordered selection of elements taken from X with repetition allowed.

If X={x1, x2, . . . , xn}, we write an r -combination with repetition allowed, or multiset of size r, as [xi1, xi2, . .
