Answer to Question 1

C

Answer to Question 2

Probability of getting an even number = 3/6 = 1/2.
Expected value of getting an even number = 1/2  (10 ) = 5.
Probability of getting an odd number = 1/2.
Expected value of getting an odd number = 1/2  (-10 ) = -5.
Expected value of the game = 5 - 5 = 0.
