If he calls it incorrectly he will win $0.00. His PISP for the certificate is $315. The offers to tell Eric the outcome of the impending coin toss. What is Eric's PIBP for the clairvoyant's information? 

a) $185, 

b) Need Eric's u-cover to determine his PISP for the information, 

c) $285, or 

d) Need Eric's u-curve probability he assigns to the "unfair" coin landing Heads (or Tails) to determine his PIBP for the information.

Answer (d) is not the correct answer. Correct answer is either a,b or c.
