If we each had 26 names, and their respective initials that could repeat, then yes. Dang that's a big number.
Your first answer is right. The possible combinations of 2 repeating letters and 50 states is like you said 26^2 x 50.
As far as
likely to repeat goes, the likelihood of a repeat of any subsequent initials and state depends on the quantity that has gone before. You know, in the extreme form, say all 33,800 combinations initials and states had played out without a repeat. The next combination would be a repeat since all combinations had come before.
