probabilities for different possible outcomes are given in the table below.
Hardcover Paperback Digital Audio
Fiction
Nonfiction
0.15 0.45 0.10 0.10
0.08 0.04 0.02 0.06
What is the probability that a randomly selected single‐book purchase will be for a book in
print format (hardcover or paperback)?
(a) 0.60
(b) 0.23
(c) 0.49
(d) 0.32
(e) 0.72
5. Consider the probabilities in problem 4. The probability that a randomly selected single
book purchase will not be for a work of fiction is
(a) 0.80
(b) 0.25
(c) 0.20
(d) 0.30
(e) 0.75
6. Two dice are rolled. Suppose A is the event the sum of the numbers on the top faces is
even, and B is the event that one of the dice shows the number “1.” The probability of
event B is
(a) 1/2
(b) 18/36
(c) 12/36
(d) 11/36
(e) 1/3
7. A child is playing with three dice: red, green, and blue. The probability that she will roll a
5 on the red, a 4 on the green, and a 3 on the blue is:
(a) 1/2
(b) 1/36
(c) 1/216
(d) 4/36
(e) 1/3
8. A survey was conducted to learn about the shopping preference of consumers during the
holiday season. Out of 2000 respondents 22% said they would prefer to shop online
because of the free shipping offered; 45% said that they would like to shop in malls and
discount outlets while 15% of the shoppers said they would use both. The probability
that a randomly selected shopper would use at least one method of shopping is:
(a) 67%
(b) 52%
(c) 82%
(d) 60%
(e) 80%
9. In the Powerball lottery, a player first selects five different numbers between 1 and 59.
After selecting the five numbers, the player then selects one number between 1 and 35.
This number is known as the Powerball. To calculate the odds of winning, we multiply the
number of ways the five numbers can be drawn from 1 and 59 by 35. The number of
ways the winning Powerball number can be drawn or the chance of winning the
Powerball is 1 divided by one of the following numbers:
(a) 5,006,386
(b) 230,000,000
(c) 175,223,510
(d) 180,345,876
(e) 190,678,000
12. The probability that the Dow Jones stock index will close above 18000 at the end of the
year is an example of
(a) classical probability.
(b) subjective probability.
(c) independent probability.
(d) priory probability.
13. The probability calculated based on observing a process (or experiment) n times and
counting the number of times an event of interest (say, X) occurs is known as
(a) classical probability.
(b) marginal probability.
(c) conditional probability.
(d) relative frequency approach of probability.
14. The probability that a person can get infected with a rare type of blood disorder is very
small. Suppose that a blood test performed on 10,000 people showed that two persons
tested positive that is, a 0.02% chance of getting this type of blood disorder. This
probability measure was calculated using
(a) conditional probability approach.
(b) marginal probability.
(c) relative frequency approach
(d) classical approach.

You can put this solution on YOUR website!
Apparently you didn't read the part of the instructions that tell you not to just dump your whole assignment and expect it to get done for you. Not happening; today or ever.
