Matilda, tanya and renee are auditioning for a play. in how many ways can the girls fill the roles of a grandmother, mother, and daughter?

would a permutation or combination be used to solve this problem?

Using arrangements, it is found that the girls can fill the roles in 6 ways.

In this question, we have 3 people for 3 roles, that is, the same number of people and roles, thus, the arrangements formula is used.

The number of possible arrangements of n elements is the factorial of n, that is:

In this problem, 3 people for 3 roles, thus , and:

The girls can fill the roles in 6 ways.

1) In 6 ways the girls can fill the roles of a grandmother, mother, and daughter.

2) A permutation would be used to solve this problem

Step-by-step explanation:

Permutation is an arrangement of the elements of a list into a one to one correspondence with itself, where as a combination is a collection of things in which order doesn't matter at all.

In the given situation there are three girls named Matilda, Tanya and Renee are auditioning for a play. The girls have to fill the roles of a grandmother, mother, and daughter that means no girl can take two roles or no two girls can 1 role i.e. repetition is not allowed so by permutation ,

the number of ways the girls can fill the roles=,where n is the total roles and r is the number of girls.

Therefore, in 6 ways the girls can fill the roles of a grandmother, mother, and daughter.
