Using all the letters of the word "THURSDAY", how many different words can be formed?
Correct answer: B. 8!
- A. 8
- B. 8!
- C. 7!
- D. 7
Explanation
THURSDAY contains 8 distinct letters, so all of them can be arranged in 8! = 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 ways. The likely trap is option c, 7!, which treats the word as though it had only seven letters.
