Given:
We have 5 letters
To Find: Number of words formed with Letter of the word ‘APPLE.’
The formula used: The number of permutations of n objects, where p1 objects are of one kind, p2 are of the second kind, ..., pk is of a kth kind and the rest if any, are of a different kind is = \(\frac{n!}{p_1!p_2! .....p_k!}\)
‘APPLE’ consists of 5 letters out of which we have 2 Ps.
Using the above formula
Where,
n = 5
p1 = 2
\(\frac{5!}{2!}\) = 60
There are 60 permutations of the letters of the word ‘APPLE’.
