Question

In how many ways can the letters of the word 'dealer' be arranged

Answer 1

Answer:

46656 or 720

Step-by-step explanation:

If repetition of the words are allowed, then you have 6 letter space and you can put the same letter also in every space. (Example- dddddd, eeeeee, aaaaaa).  Therefore, through the concept of Permutations or Combinations, your answer would be: 6^4=46656.

If repetition is not allowed then you have the choice of 6 letters for the first place, left with 5 choice of letters for the 2nd and so on. Therefore, the answer would be 6!=720 (6!=6*5*4*3*2*1).
