Question

How many ways are there to select five unordered elements from a set with three elements when repetition is allowed?

Answer 1

The number of ways or permutations to select five unordered elements from a set with three elements when repetition is allowed is 243.

According to the given question.

The total number of elements, n = 3

The number of elements to be selected at a time when repetition is  allowed, r = 5

Since, we know that " the number of ways or permutations of n things taken r all at a time, when repetition of things are allowed, is $n^{r}$.

Therefore,

The number of ways or permutations to select five unordered elements from a set with three elements when repetition is allowed

= $3^{5}$

= 243

Hence, the number of ways or permutations to select five unordered elements from a set with three elements when repetition is allowed is 243.
