You get to throw a die. If you roll a 3, you win \$6. If you roll a 1 or a 5, you
win \$3. If you roll an even number, you lose \$6. Find your expectation for this
game.

You have a 1/6 chance of getting \$6, 1/3 (2/6) chance of getting \$3, but a 1/2 (3/6) chance of losing \$6. I would expect to lose money. Your chances are equal for winning \$12 or losing \$18.

I hope this helps. Thanks for asking.
