How many 4-letter words (without repetition) can you make using D, E, A, L?
Show answer & explanation
Correct answer: D
Explanation
Number of ways to fill the first slot = 4 (any of D, E, A, L)
Number of ways to fill the second slot = 3 (from the remaining letters)
Number of ways to fill the third slot = 2
Number of ways to fill the fourth slot = 1
Total number of words = 4 × 3 × 2 × 1 = 4! (4 factorial)
Total words = 24
Therefore, a total of 24 words can be formed using D, E, A, L.
