Aclassic counting problem is to determine the number of different ways that the letters of "parallel" can be
arranged. find that number.
the number of different ways that the letters of "parallel" can be arranged is

3,360

Step-by-step explanation:

There are 8 letters in the word "PARALLEL". Also there are 3 letters L and 2 letters A.

We can arrange 8 letters in 8! different ways. But we need to count how many of them are the sasme arrangments, because latters are not all different.

So, the number of different ways that the letters of "PARALLEL" can be arranged is

Here we divided by number of different ways to rearrange 3 letters L and by number of different ways to arrange 2 letters E.

it would be c. 25 units
