Chapter 5: Q T5.8. (page 337)

For events A and B related to the same chance process, which of the following statements is true?

(a) If A and B are mutually exclusive, then they must be independent.

(b) If A and B are independent, then they must be mutually exclusive.

(c) If A and B are not mutually exclusive, then they must be independent.

(d) If A and B are not independent, then they must be mutually exclusive.

(e) If A and B are independent, then they cannot be mutually exclusive.

Short Answer

Expert verified

The correct option is (e)

Step by step solution

01

Step 1. Given

There are two events that are related to the same chance process.

02

Step 2. Concept

A and B are independent, then they cannot be mutually exclusive.

03

Step 3. Explanation

Two events occur as a result of the same random process.

Two occurrences are considered independent if the occurrence of one does not affect the occurrence of the other. Furthermore, two mutually exclusive occurrences cannot be predicted to occur at the same moment. As a result, the independent events are unable to be mutually exclusive.

As a result, the correct option is (e).

Scrabble In the game of Scrabble, each player begins by drawing 7 tiles from a bag containing 100 files. There are 42 vowels, 56 consonants, and 2 blank tiles in the bag. Chait chooses her 7 tiles and is surprised to discover that all of them are vowels. We can use a simulation to see if this result is likely to happen

by chance.

(a) State the question of interest using the language of probability.

(b) How would you use random digits to imitate one repetition of the process? What variable would you measure?

(c) Use the line of random digits below to perform one repetition. Copy these digits onto your paper. Mark directly on or above them to show how you

determined the outcomes of the change process. 00694 05977 19664 65441 20903 62371 22725 53340

(d) In 1000 repetitions of the simulation, there were 2 times when all 7 tiles were vowels. What conclusion would you draw?

Ten percent of U.S. households contain 5or more people. You want to simulate choosing a household at random and recording whether or not it contains 5or

more people. Which of these are correct assignments of digits for this simulation? (a) Odd = Yes (5or more people); Even = No (not 5or more people)

(b) 0= Yes; 1,2,3,4,5,6,7,8,9= No

(c) 5= Yes; 0,1,2,3,4,6,7,8,9= No

(d) All three are correct.

(e) Choices (b) and (c) are correct, but (a) is not.

Free downloads? Illegal music downloading has become a big problem: 29% of Internet users download music files, and 67% of downloaders say they

don鈥檛 care if the music is copyrighted.15 What percent of Internet users download music and don鈥檛 care if it鈥檚 copyrighted? Write the information given in terms of probabilities, and use the general multiplication rule.

Simulation blunders Explain what鈥檚 wrong with each of the following simulation designs.

(a) A roulette wheel has 38colored slots鈥�38 red, 18 black, and 2green. To simulate one spin of the wheel, let numbers 00 to 18 represent red, 19 to 37

represent black, and 38 to 40 represent green.

(b) About 10% of U.S. adults are left-handed. To simulate randomly selecting one adult at a time until you find a left-hander, use two digits. Let 01 to 10 represent being left-handed and 11 to 00 represent being right-handed. Move across a row in Table D, two digits at a time, skipping any numbers that have already appeared, until you find a number between 01 and 10. Record the number of people selected.
