Since Jake already knows the last 3 letters of his Klingon name, we just need to find the probability of him correctly guessing the 1st letter.
There are 10 letters in the Klingon alphabet from which to choose, however Jake knows that the first letter is neither "N" nor "Z".
So, Jake must randomly select 1 of the 8 remaining letters.
This means: P(Jake correctly guesses the first letter of his name) = 1/8
Answer: C
