here is the question, in the picture below. literally just this

2. A music producer, who are about to make a debut album for a new group band, is considering three groups, namely Group A, Group B and Group C. In order to find the best group, he is considering a simple decision tree analysis. You project three events, namely Platinum, Gold, and Silver album for each group you promote. a. Draw the decision tree for the problem b. For each group, how do you estimate the probability for each event (Platinum, Gold or Silver) using the analytic hierarchy process (AHP). Draw the decision hierarchy. (Hint: you might consider at least three criteria that make a group band successful in the music industry)
