ivolga24 [154]

Answer:

There are 60 permutations.

Step-by-step explanation:

Arrangements formula:

The number of possible arrangements of n elements is given by:

A_n = n!

With repetition:

For each element that repeats, with n_1, n_2, ..., n_n times, the formula is:

A_n^{n_1,n_2,...,n_n} = \frac{n!}{n_1!n_2!...n_n}

In this question:

Apple has 5 letters.

P appears two times. So

A _5^{2} = \frac{5!}{2!} = 60

There are 60 permutations.
