Answer 2

Answer: 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=$\frac{n!}{(n-r)!}=\frac{3!}{(3-3)!}=3!=6$,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.
