Question

How many unique ways are there to arrange the letters in the word pretty

Answer 1

Answer:

A 6 letter word can be arranged in 6! or 6 factorial ways if all the letters were different. 6! = 6*5*4*3*2*1 =720 but in this case there are duplicates because of the 2 “t”s so this must be divided by 2 giving 360 unique arrangements or permutations.
