Step-by-step explanation:
There are six unique letters. Â Any of the six could be the first letter. Â Once we've picked a first letter, that leaves 5 letters that could go second. Â So on and so forth. Â So the number of ways they can be arranged is:
6Ă—5Ă—4Ă—3Ă—2Ă—1 = 720
The correct unscrambling is "worthy". Â So the probability of randomly selecting this order from the 720 possible combinations is 1/720.
