Some alphabet contains four different characters. How many three-letter words can be made from the characters of this alphabet if the characters in the word can be repeated?
Since, by condition, there are 4 letters in the alphabet, and words consist of three, then the number of options is determined as follows: 4 * 4 * 4 = 64. If the characters in the word could not be repeated, then it would have turned out 4 * 3 * 2 = 24.
