Answer:
2/9
Explanation:
There are 9 possible combinations, therefore the chance of getting one of them is 1/9 chance.
Since this is the probability of getting two of the combinations, the answer is 2/9.
The probability of getting any letter once is 1/3
The probability of getting any combinations = 1/3 * 1/3 = 1/9
The probability of getting two of the combinations = 1/9 + 1/9 = 2/9
