Question 1032898
Twenty-three slips of paper are each marked with a different 
letter of the alphabet and placed in a basket. A slip is pulled 
out, its letter recorded (in the order in which the slip was 
drawn), and the slip is replaced. This is done 44 times. Find 
the probability that a word with no repetition of letters is 
formed.

Answer: 0.  

There is no way to draw out 44 different letters when there are 
only 23 different letters in the basket.  There must be 
repetitions.
