    Help with probability

    Suppose it costs $1 to play a certain game of chance and your chances of winning are .2. If you win, you receive $4 (for a net gain of $3). If you lose, you receive nothing (for a net loss of $1). What are your expected winnings for a round of five games?

    Thanks

    Never mind I was able to get a friend to help me and now I feel stupid for not being able to reason my way out of it.
