9/14 Chapter 2 ILP + Puzzle Investigator Problem (PIP)

1.  Warm-up:  Recall from Friday that the sample space represents all of the possible outcomes.  Consider this problem:

Carlock's bakery has decided to hold a promotion in order to increase business.  They will charge customers 50 cents to choose a plastic ball (randomly) from a bag.  The bag consists of 8 yellow balls, 10 red balls, and 2 green balls.  If a customer chooses a yellow ball they receive a chocolate chip cookie; if they choose a red ball they receive a donut hole; if they choose a green ball they receive an apple pie.

a)  The owner is worried that he will lose money by giving away too many apple pies.  His idea is to double the amount of each colored ball in the bag.  "Then there will be 20 red balls, so the customer will be more likely to get a donut hole."  Is the owner correct?  Explain.

b)  Change the sample space of this promotion in such a way that the probability of receiving an apple pie is less than 10%.
