5. You play a game using an unfair coin. Suppose that each time the coin is tossed, the probability of showing "head" is 1/3 and the probability of showing "tail" is 2/3. Also suppose that each time the coin shows head you win 10 dollars and you lose 3 dollars when it shows tail. How much money do you expect to win when the coin is tossed 10 times?

(2) Consider the following game of chance. You pay $30 to enter the game. First, you choose a number at random from {1, 2, ..., 20}, and then, independent of this draw, you flip a fair coin 5 times (flips are independent of each other). The host will multiply the number of heads from the 5 flips by the number your draw from {1, 2, ..., 20} and give you that many dollars. (a) What is your expected gain in...

Suppose you can place a bet in the following game. You flip a fair coin (50-50 chance it lands heads). If it lands heads, you get 4 dollars, if it lands tails, you pay 1 dollar. This is the only bet you can make. If you don't make the bet you will neither gain nor lose money. What is the utility for you of the coin landing tails if you make the bet (assume utility is dollars)?

Suppose that you believe there is a 30% chance that the coin in your hand is biased 80% in favor of heads, and a 70% chance that it’s fair. You flip it twice and get heads both times. What should you now believe is the probability that the coin is fair?

We play a game where we throw a coin at most 4 times. If we get 2 heads at any point, then we win the game. If we do not get 2 heads after 4 tosses, then we loose the game. For example, HT H, is a winning case, while T HT T is a losing one. We define an indicator random variable X as the win from this game. (d) (5 Pts.) On average how many times do you...
