Find the number of distinct permutations of the letters in the word 'OMAN'.
Answer and explanation
Correct answer: C. 24
- Step 1: The word 'OMAN' contains 4 distinct letters: O, M, A, N.
- Step 2: Calculate total arrangements using factorial: P = 4!.
- Step 3: Evaluate: 4! = 4 3 2 * 1 = 24.
Answer
24.
Why not the others: '12' assumes one letter repeats twice and divides by 2!; '16' calculates 4^2 instead of 4!; '4' gives the count of letters rather than permutations.
