Video poker is a popular form of gambling in casinos, second only to slot machines. Some video poker games offer a “doubleup” feature, where players receiving a paying hand are offered the chance to double their winnings. If a player chooses to play the double-up feature, the machine deals one card from a 52- card deck to the player and one to the “dealer.” If the player’s card is higher than the dealer’s (with an ace being the highest card), the player doubles his or her winnings. If the player’s card is lower than the dealer’s card, the player loses his or her winnings. If both are dealt cards of the same value (a push), the player keeps his or her original bet. Explain whether the double-up feature is an example of a fair game.
