Xena does not follow the delta property. She has just paid $100 for a certificate that allows her to call the flip of a coin. Ifshe calls it correctly, she wins $400: otherwise she gets nothing. Her PISP for the certificate is $250. A clairvoyant offers to tell Xena the outcome of the impending coin toss. What is her PIBP for the clairvoyant's information?

a. $150

b. $300

c. We need Xena's u-curve to determine her PIBP for the clairvoyant's information.

d. We need both Xena's M-curve and the probability she assigns to the coin landing "Heads" to answer this question.
