question
You are now a prisoner faced with a dilemma. You must choose to either keep the 3 points for this question for yourself or donate 0.33 points to the class pool. The total amount of points you will receive is the sum of the pool points plus the amount you have kept for yourself. For example, assume 12 of your classmates (24 total students, so you've
got 23 classmates) each donate 0.33 points to the pool then there will be 4.0 points in the pool. If you choose to donate your 0.33 points to the pool also, you will get 4.33 points; however, if you keep your 3
points then you will receive 7.0 points. The maximum you can receive is about 10.6 points and the minimum is 0.33 points. Please make your choice.
