How many three letter words are formed using the letters of the word TIME?
Correct answer: D. 24
- A. 12
- B. 20
- C. 16
- D. 24
Explanation
TIME has 4 distinct letters, and forming a three-letter word without repetition gives 4P3 = 4 x 3 x 2 = 24 words. The likely trap is option a, 12, from selecting three letters with combinations instead of arranging them in order.
