Which of the following statements is true? a) The probability of u(x) being greater than c is less than or equal to the expected value of u(x) divided by c. b) The probability of u(x) being greater than c is greater than or equal to the expected value of u(x) divided by c. c) The probability of u(x) being less than c is less than or equal to the expected value of u(x) divided by c. d) The probability of u(x) being less than c is greater than or equal to the expected value of u(x) divided by c.
