Janelle is playing craps and places a $5 bet on the number 8 with a probability of winning at 5/36.

However, the probability of losing is 1/6 and happens if a 7 is rolled.

Any other number rolled means she doesn't win or lose and the game continues.

If an 8 is rolled, she will win $6 (and keep her initial bet) but if a 7 is rolled, she loses all $5.

What is the expected value for Janelle on a roll in this game of craps?
