Chapter 5: Q 106. (page 333)

Suppose a loaded die has the following probability model: If this die is thrown and the top face shows an odd number, what is the probability that the die shows a 1?

(a) 0.1 (d) 0.6

(b) 0.3 (e) None of these

(c) 0.5

Short Answer

Expert verified

The correct option is (d)0.6

Step by step solution

01

Step 1. Given Information

The probability model for a loaded die is as follows:

02

Step 2. Concept used

Conditional probability : P(B|A)=P(AandB)/P(A)

03

Step 3. Calculation

Use the conditional probability definition:

P(1|odd)=P(1andodd)/P(odd)=P(1)/P(odd)=0.3/0.3+0.1+0.1=0.6

As a result, the proper option, according to the option, is (d)0.6

Who eats breakfast? The two-way table describes the 595 students who responded to a school survey about eating breakfast. Suppose we select a student at random. Consider events B: eats breakfast regularly, and M: is male.

(a) Find P(B|M) Explain what this value means.

(b) FindP(M|B) Explain what this value means.

Sampling senators Refer to Exercise 67. Are events D and F independent? Justify your answer.

Liar, liar! Sometimes police use a lie detector (also known as a polygraph) to help determine whether a suspect is telling the truth. A lie detector test isn’t foolproof—sometimes it suggests that a person is lying when they’re actually telling the truth (a “false positive”). Other times, the test says that the suspect is being truthful when the person is actually lying (a “false negative”). For one brand of polygraph machine, the probability of a false positive is 0.08.
(a) Interpret this probability as a long-run relative frequency.
(b) Which is a more serious error in this case: a false positive or a false negative? Justify your answer.

Sampling senators The two-way table below describes the members of the U.S Senate in a recent year. Male Female Democrats 4713 Republicans 364

(a) Who are the individuals? What variables are being measured?

(b) If we select a U.S. senator at random, what’s the probability that we choose

  • a Democrat?
  • a female?
  • a female Democrat?
  • a female or a Democrat?

Fill ’err up! In a recent month, 88%of automobile drivers filled their vehicles with regular gasoline, 2%purchased midgrade gas, and 10%bought premium gas.17 Of those who bought regular gas, 28% paid with a credit card; of customers who bought midgrade and premium gas, 34% and 42%, respectively, paid with a credit card. Suppose we select a customer at random.

Draw a tree diagram to represent this situation. What’s the probability that the customer paid with a credit card? Use the four-step process to guide your work.
