Two coins are flipped. You win $3 if either two heads or two tails turn up; you lose $4 if a head and a rail turn up. What is the expected value of the game?

Answer:
Step-by-step explanation:
It's too bad about this problem. It's a fair game if you get paid the same amount that you have to pay if you lose.
You win 2 ways
You lose 2 ways.
Expectation
E = 1/2 * 3 - 1/2 * 4
E = 1.5 - 2
E = -0.5
Which means that you should expect to lose 0.5 dollars every time you play this dreadful game.
