Chapter 7, Problem 21SE
sider the following game. A per son flips a coin repeatedly until ahead conies up, This person receives a payment of 2ndollars if the first head conies up at the nth flip,
- Let! be a random variable equal to the amount of money the person wins, Show that the expected value of X does not exist (that is, it is infinite), Show that a rational gambler, that is, someone willing to pay to play the game as long as the price to play is not more than the expected payoff, should be willing to wager any amount of money to play this game, (This is known as the St, Petersburg paradox, Why do you suppose it is called a paradox?)
- Suppose thattheperson receives 2ndollars ifthefirst head comes up on the nth flip where n< 8 and a8=256 dollars ifthefirst head comesup on or after the eighth flip, What is the expected value of the amountof money the person wins?Howmuch money shouldapersonbewillingto pay to play this game?
