Step-by-step explanation:

Answer 2

Answer:

The number of ways are 720.

Step-by-step explanation:

As per the question,

We need to find the ways of arranging the dolls. Also, this question has an important information missing, that Zeba already had 4 dolls in her shelves.

As we know,

• There should be one doll on each shelf.

• Initially number of dolls she had = 4

• New dolls she got = 2

• So, the total number of dolls she has  = 4+2 = 6

• Now, to arrange each doll in one shelf, there is 6 space and 6 dolls

So, the number of permutations are= 6C6×6! = 6! = 720

Hence,

The number of ways are 720.
