An alphabet wheel has 26 equally likely spaced slots
numbered A to Z. Rusty bets $ 1 on one of the numbers
and wins $ 20. You earn $20 if it lands on your letter,
otherwise you lose your bet. The random variable X
assigns $20 to the wheel landing on letter chosen and $1 to having the wheel land on any other letter. What is
expected value of alphabet on wheel?
