Answer to Question 1

The expected values would be negative for the person playing, as the casinos are designed to make money.

Answer to Question 2

The sum of the probabilities in a probability distribution must be 1 and each individual probability must be between 0 and 1, inclusive. The total area of the bars in a probability histogram is 1.
