3. You and a friend are tossing two fair coins. If both coins show heads, you win $2, if both show tails, you win $1, and if the coins don't match, you lose $1 (i.e. win –$1). Let X be your winnings after a single play of the game. Find the probability distribution of X. Also find the expected value of х.
