Question

RedBird Games produces board games and has recently received a proposal for a new board game. The manager responsible for reviewing submitted board game proposals is quite familiar with the style of the game proposed and believes there's a 65% chance that the game will be successful. If successful, a profit of $750,000 can be expected. If RedBird Games decides to produce the proposed game and it is unsuccessful, a loss of $250,000 will occur. Before deciding to accept or reject the proposed board game, the manager has the option to send it out for review by experts that RedBird Games can hire. The review process will provide either a favorable (F) or unfavorable (U) evaluation of the proposed board game. RedBird Games' past experience with these expert reviewers suggests probabilities P(F)=0.7 and P(U)= 0.3 apply. Let Al represent that the proposed game is successful, and A2 be that the proposed game is unsuccessful. The manager's initial probabilities of Al and A2 will be revised based on whether the review is favorable or unfavorable. The following probabilities are given. P(A1F) = 0.75 P(ATU)=0.417 P(A2|F) = 0.25 P(A2U)=0.583 (a) Construct a decision tree assuming that RedBird Games will first make the decision of whether to send the proposed game out for review by experts and then make the decision to accept or reject the game. You may use PowerPoint to draw or draw on paper and take a picture to attach. Your attached picture must be clear and large enough to read.
