Casino War is a card game played with a single 52 card deck. The cards are ranked in the same way that cards in poker games are ranked, with aces being the highest cards. One card each is dealt to a dealer and to a player. If the player's card is higher, he or she wins the wager they bet. However, if the dealer's card is higher, the player loses their bet. A tie occurs when the dealer and the player each have cards of the same rank. In a tie situation, the player has two options: The player can surrender, in which case the player loses half the bet. The player can go to war, in which case the player must double his stake. If the player continues play in view of a tie, the dealer burns (discards) three cards before dealing each of them an additional card. If the player's card is ranked higher than the dealer's, then the player wins the amount of his original wager only. If the dealer's card is ranked higher than the player's, the player loses his (doubled) wager. If the ranks are equal, then the player wins the amount of his doubled wager. What is the expected value of betting $10 on this game if the player knows they will surrender in the event of a tie? Round all probabilities to the nearest whole number value (i.e. 46% or .46, not 46.2% or .46234) -$10 -$0.30 $0.30 $9.70

Suppose that Dave gets happiness from money according to the utility function U($) = $. This means that $25 worth of money gives him 25 units of happiness and $50 worth of money gives him 50 units of happiness. Suppose a casino lets him bet on the spin of a roulette wheel. He can bet $10 on black and will win $10 if the ball falls in a black bin, or lose his $10 if the ball falls in either a red or green bin. Suppose further that there are are 24 possible black bins, 24 red bins, and two green bins. How much would we expect playing this game would impact Dave's happiness? It makes him 4.8 units happier if he plays the game vs. not playing the game. It makes him 0.40 units less happy if he plays the game vs. not playing the game. It makes him 2.4 units less happy if he plays the game vs. not playing the game. It makes him 0.20 units happier if he plays the game vs. not playing the game.
