Question

Find the number of arrangements of the letters of the word STRENGTH if the
order of the consonants must not be changed?

Answer 1

Since there are 6 consonants, the E can be in any of seven positions.

Answer 2

I see 8 positons, which include both before and after all the consonants and the present one.

Answer 3

My bad. There are seven consonants.
Guess I need to go back to counting school.
