Question: Suppose that your utility function is u (x) = x, and that you are offered a gamble which allows you to win $4 if you
Suppose that your utility function is u (x) = √x, and that you are offered a gamble which allows you to win $4 if you are lucky and $1 if you are not.
(a) Suppose that the probability of winning $4 is 1/4 and the probability of winning $1 is 3/4. What is the expected value of this gamble?
(b) Suppose that the probability of winning $4 is still 1/4 and the probability of winning $1 is 3/4. What is the expected utility of this gamble?
(c) Suppose that the probability of winning $4 is still 1/4 and the probability of winning $1 is 3/4. What is the certainty equivalent of the gamble; that is, what is the amount of money X such that you are indifferent between receiving $X for sure and playing the gamble?
(d) Imagine now that the probability of winning $4 is p and the probability of winning $1 is (1 – p). If the utility of the gamble equals 3/2, what is p?
