Let's say you devise a blackjack strategy where you win 42% of the time, tie 9% of the time, and lose 49% of the time. When you lose you lose $1, on a tie you gain $0, and on a win you gain $1 (assume you aren't allowed to split or double). What is the expected value of your winnings? Note: Do not round your answer.
