Answer:
360
Step-by-step explanation:
Number of permutations with repetition:
n! / (a! b! c! ...)
where n is the total number of letters and a, b, c, etc. is the number of times each letter is repeated.
In this case, there are 6 letters in the word PRETTY, and T is repeated 2 times. So the number of permutations is:
6! / 2!
720 / 2
360
