The total number of ways to draw 2 letters from the bag is 5C2 = 10. This is because there are 5 letters in total, and we are choosing 2.
The number of ways to draw 2 O's from the bag is 1C2 = 1. This is because there is only 1 O in the bag.
Therefore, the probability of drawing an O twice is 1/10 = 1 over 10.
So, the correct response is: 1 over 10.
