Most likely you have been given probabilities for each of these individually.
"OR" means you add in probability. However, you must be careful not to count overlapping things more than once. Very often ten best way to do this is to draw a Venn diagram (overlapping circles) showing the situation. Your answer would be the totals of all the regions that make up E, F, G, and H.

Um... 1 in 26?
You do not provide enough information. If you were rolling a 26 sided die with each letter of the alphabet on it, your chances of rolling any one of those letters would be the same -- 1 in 26.
Can you please add details?
