An electronics company manufactures batches of n circuit boards. Before a batch is approved for shipment,
m boards are randomly selected from the batch and tested. The batch is rejected if more than d boards in
the sample are found to be faulty.
a) A batch actually contains six faulty circuit boards. Find the probability that the batch is rejected when
n = 20, m = 5, and d = 1.
b) A batch actually contains nine faulty circuit boards. Find the probability that the batch is rejected when
n = 30, m = 10, and d = 1.
Twenty-eight applicants interested in working for the Food Stamp program took an examination designed
to measure their aptitude for social work. A stem-and-leaf plot of the 28 scores appears below, where the
first column is the count per branch, the second column is the stem value, and the remaining digits are the
leaves.

Pam, Rob and Sam get a cake that is one-third chocolate, one-third vanilla, and one-third strawberry as shown below. They wish to fairly divide the cake using the lone chooser method. Pam likes strawberry twice as much as chocolate or vanilla. Rob only likes chocolate. Sam, the chooser, likes vanilla and strawberry twice as much as chocolate. In the first division, Pam cuts the strawberry piece off and lets Rob choose his favorite piece. Based on that, Rob chooses the chocolate and vanilla parts. Note: All cuts made to the cake shown below are vertical.Which is a second division that Rob would make of his share of the cake?
