Chapter 5: Q. 5.67. (page 211)

Dice. Refer to exercise 5.53.

a Are events A and B mutually exclusive?

b Are events B and C mutually exclusive?

c Are events A, C and D mutually exclusive?

d Are there three mutually exclusive events among A, B, C and D? four?

Short Answer

Expert verified

Part (a) A and B are not mutually exclusive because they have similar consequences.

Part (b) B and C are mutually exclusive.

Part (c) A, C, and D are not mutually exclusive

Part (d) A,B, C, and D are not mutually exclusive

Step by step solution

01

Part (a) Step 1. Given information.

A = {2,4,6}

B = {4,5,6}

C = {1,2}

D = {3}

02

Part (a) Step 2. A and B are not mutually exclusive events.

A and B are not mutually exclusive because they have similar consequences.

(A鈭�B)={4,6}

03

Part (b) Step 1. Events B and C are mutually exclusive 

Because they have no common outcomes, the occurrences B and C are mutually exclusive.

(B鈭�C)=蠒

04

 Part (c) Step 1. A, B and D are not mutually exclusive events. 

The occurrences A, C, and D are not mutually exclusive because they have similar results.

(A鈭�C)=2

05

 Part (d) Step 1.The events A, B, C, and D are mutually exclusive in three or four ways.

There are three mutually exclusive events among the occurrences A, B, C, and D because no two of them have the same outcome.

Events A, B, C, and D are not mutually exclusive because a pair of them have the same outcome.

(A鈭�B)={4,6},(B鈭�C)=蠒,(C鈭�D)=蠒,(A鈭�B)={4,6},(B鈭�C)=蠒(C鈭�D)=蠒(A鈭�C)={2},(A鈭�D)=蠒,(B鈭�D)=蠒,(A鈭�C)={2},(A鈭�D)=蠒(B鈭�D)=蠒

A variable y of a finite population has the following frequency distribution:

y1234
f22106

Suppose a member is selected at random from the population and let Y denote the value of the variable y for the member obtained.

a. Determine the probability distribution of the random variable Y.

b. Use random-variable notation to describe the events that Y takes on the value 3, a value less than 3, and a value of at least 3.

c. Find P(Y = 3), P(Y <3), and P(Y 鈮� 3). Interpret your results.

d. Construct a probability histogram for the random variable Y.

Expected Utility. One method for deciding among various investment involves the concept of expected utility. Economists describe the importance of various levels of wealth by using utility functions. For instance, in most case, a single dollar is more important (has greater utility ) for someone with little wealth than for someone with greater wealth Consider two investments, say investment A and B. Measured in thousand of dollars, suppose that investment A yields 0, 1, and 4 with probability 0.1 and16 with probability 0.5, 0.3 and 0.2 respectively. Let Y denote the yield of an investment. For the two investment, determine and compare.

Part (a) The mean of Y, the expected yield.

Part (b) The mean of Y,the expected utility, using the utility function role="math" localid="1651845051902" 蠀y=yInterpret the utility function u

Part (c) The mean of y3/2,the expected utility, using the utility function v(y)=y3/2. Interpret the utility function v

An experiment has 20 possible outcomes, all equally likely. An event can occur in five ways. The probability that the event occurs is .

Normality Requirement What is different about the normality requirement for a confidenceinterval estimate of \(\sigma \)and the normality requirement for a confidence interval estimateof \(\mu \)?
