Abdul has one die in his left hand and one in his right hand. One die has six dots painted on each face, and the other has one dot painted on two of the faces and six dots painted on each of the other four faces. Greta is to pick one die (either "left" or "right") and will receive $10 for each dot painted on the die that is picked. Before choosing, Greta may pay Abdul $15, and he will toss the die in his left hand and tell her how many dots are painted on the face that comes up. Use a decision tree to determine how to maximize Greta's profit. Also determine EVSI and EVPI.
