Direction: Find the number of permutations that can be made from the letters of the word 'OMEGA'.
-
O and A occupying end places.
-
- 12
- 14
- 20
- 18
- None of the above
Correct Option: A
When O and A occupy end places. Then, the three letters (M, E, G) can be arranged themselves by 3! = 6 ways and two letters (O, A) can be arranged among themselves in 2! = 2 ways.
∴ Total number of ways = 6 x 2 = 12
