<PRE><B>Question 1198366</B>
How many different 4-letter permutations can be formed from the letters in the word REPRESENT?
Singles(e, n , r , s, t) with duplicate letters (eee,rr)
My Imput:
No Duplicates:  6P4 = 360  0r (6C4)x4! = 360
1 from single and eee: (5C1)(1C1)x4!/3! = 20 
2 from single and 1 pair of duplicate letter: (5C2)((2C1)4!/2! = 240
2 pair of duplicate letters: (2C2)4!/2!2! = 6 
How many different 4-letter permutations can be formed from the letters in the word REPRESENT?
 How many would be the Sum= 360 + 20 +240+ 6 = 626
