Are you thinking of actual Scrabble? Some letters have duplicates, and other don't? And the number of duplicates varies on how frequentlyused the letter is?
Or is this a mathematical Scrabble: Every letter has an unlimited supply, and the probability of drawing an E doesn't depend on whether some E's have already been drawn.
