"Our movie studio is considering filming the Don Harnett story. We know that if the film is a flop, we will lose $4 million, and if the film is a success, we will earn $15 million. Beforehand, we believe that there is a 10% chance that the Don Harnett story will be a hit. Before filming, we have the option of paying the noted movie critic Roger Alert $1 million to pre-review the script and predict whether the film will be a hit or flop. Of past films that Alert has pre-reviewed and that turned out to be hits, he has predicted a hit in 60% of the cases. Of past films that he has pre-reviewed that turned out to be flops, he has predicted a flop in 90% of the cases."
