Answer 2

Given:

The word: HELLO

To find:

The number of distinct permutations of the letters

Solution:

The number of distinct permutations of the letters of the word HELLO is 60.

We can find the number by following the steps given-

We know that the number of permutations can be obtained by taking the factorial of the number of letters and dividing it by the factorial of the number of times a letter is repeated.

The number of letters in the word HELLO=5

The letter L is repeated twice.

So, the number of permutations= Factorial of the number of letters/ Factorial of the number of times a letter is repeated

The number of permutations= 5!/2!

=5×4×3×2×1/2×1

=5×4×3

=60

Therefore, the number of distinct permutations of the letters of the word HELLO is 60.
