a) we have 5 spots to fill for the first spot we have 5 letters for the second we have 4 letters, for 3rd 3 for 4th 2 and for 5th we have 1 so 5*4*3*2*1= 120 ways

So won't it be 4 letter's word for a because there are 2 p's?
dan815
  • dan815
no I think a) is asking you if you have given 5 letters, how can you arrange these 5 letters to make different arrangements of words
dan815
  • dan815
but b) is asking you given these 5 letters or 4 unique letters, how many words can i make, but this question needs to tell you the length of the word we are talking about here
anonymous
  • anonymous

dan815

How many 3 letter words can be formed using the letters c,a,t allowing for repetition of the letters?
anonymous
  • anonymous
There are 3 letters which can be used to fill the first location. Because repetition is allowed, the same 3 letters can be used to fill the second location and also the last location.
