Chapter 13.2, Problem 56PS

To determine

The box you would choose if every student needs to choose one of the two boxes without communicating each other.

$\boxed{}$	An A grade if everyone checks this box.
$\boxed{}$	A 50% chance of an A and a 50% chance of an F and others will be given an F in this course.

If everyone checks the first box, then all will get an A grade. If anyone checks the second box, then that student has 50% chances of A and 50% chances of F while others will be given F.
