The probability for an event to happen can be computed by
P(x) = Number of Favorable Outcomes/ Number of Possible Outcomes

In this case, the number of favorable outcomes is 2 because the letter H appears 2 times.  meanwhile, the number of possible outcomes is 13 because there is a total of 13 letters.

Thus, P(x) = 2/13

Hope this helps :)
