Problem #2: Suppose an ice cream shop starts a promotion from 2-4p on Wednesdays using two sets of numbered cards. Customers get to draw 2 cards (at random), one from each set. Each set has 8 cards numbered 0, 1, 2, ... 7. The customer will receive a discount based on the combination of cards drawn which is equal to the fırst card, followed by the second card. For example, if a customer draws a 7 and a 7, s/he gets an 77% discount. If a customer draws a 1 and 7, s/he gets a 17% discount. If the cards are 0, 0 the customer gets no discount. a. Describe the random process. b. How many outcomes are in the sample space? c. Are the sample space outcomes equally likely? Why or why not?

Problem #2: Suppose an ice cream shop starts a promotion from 2-4p on Wednesdays using two sets of
numbered cards. Customers get to draw 2 cards (at random), one from each set. Each set has 8 cards numbered
0, 1, 2, ... 7. The customer will receive a discount based on the combination of cards drawn which is equal to the
fırst card, followed by the second card. For example, if a customer draws a 7 and a 7, s/he gets an 77% discount.
If a customer draws a 1 and 7, s/he gets a 17% discount. If the cards are 0, 0 the customer gets no discount.
a. Describe the random process.
b. How many outcomes are in the sample space?
c. Are the sample space outcomes equally likely? Why or why not?
d. Write out the sample space. (Just kidding.) Determine the probability a customer at least a 12%
e. Determine the probability a customer gets more than a 75% discount on his/her ice cream.
