David has a total wealth of $50,000, which corresponds to 500
utils of happiness (i.e., David's utility from $50,000 of wealth is
equal to 500). If David gets sick he will incur $30,000 in medical
bills, leaving him with $20,000 of wealth and utility from wealth
of 300 (i.e., David's utility from $20,000 of wealth is 300).
Suppose that David has a 40% chance of getting sick. What is
David's expected utility from wealth? (Note that expected utility
from wealth is equivalent to expected utility over wealth.)
