What is meant by two mutually exclusive events? Give one example of two mutually exclusive events and another example of two mutually nonexclusive events.

Short Answer

Expert verified
Mutually exclusive events are events that cannot happen simultaneously - if one occurs, the other cannot. As an example, flipping a coin can result in either heads or tails, but not both - these are mutually exclusive events. In contrast, mutually non-exclusive events can occur together. For instance, when drawing a card, it being a 'heart' and it being a 'face card' are not mutually exclusive, as there can be cards like 'King of Hearts' which satisfy both conditions.

Step by step solution

01

Define Mutually Exclusive Events

In probability, two events are said to be mutually exclusive if they cannot happen at the same time. In other words, the occurrence of one event excludes the occurrence of the other.
02

Example of Mutually Exclusive Events

For instance, consider flipping a fair coin. It can either land on heads or tails. However, it cannot land on both heads and tails at the same time. So, the events 'landing on heads' and 'landing on tails' are mutually exclusive.
03

Define Mutually Non-Exclusive Events

By contrast, mutually non-exclusive events can happen at the same time. These are events which do not prevent each other from happening.
04

Example of Mutually Non-Exclusive Events

Let's consider a deck of cards. Drawing a card that is a 'heart' and drawing a card that is a 'face card' are not mutually exclusive. These two events can occur simultaneously. For example, a 'King of Hearts' is both a heart and a face card.

In a sample survey, 1800 senior citizens were asked whether or not they have ever been victimized by a dishonest telemarketer. The following table gives the responses by age group. $$\begin{array}{l|llcc} & & & \begin{array}{c} \text { Have Been } \\ \text { Victimized } \end{array} & \begin{array}{c} \text { Have Never } \\ \text { Been Victimized } \end{array} \\ \hline & 60-69 & \text { (A) } & 106 & 698 \\ \text { Age } & 70-79 & \text { (B) } & 145 & 447 \\ & 80 \text { or over (C) } & 61 & 343 \\ \hline \end{array}$$ Suppose one person is randomly selected from these senior citizens. Find the following probabilities a. \(P(\) have been victimized or \(\mathrm{B}\) ) b. \(P(\) have never been victimized or \(\mathrm{C}\) )

The following table gives a two-way classification of all basketball players at a state university who began their college careers between 2001 and 2005, based on gender and whether or not they graduated \(\begin{array}{lcc} \hline & \text { Graduated } & \text { Did Not Graduate } \\ \hline \text { Male } & 126 & 55 \\ \text { Female } & 133 & 32 \\ \hline \end{array}\) a. If one of these players is selected at random, find the following probabilities. i. \(P(\) female and graduated \()\) ii. \(P(\) male and did not graduate \()\) b. Find \(P\) (graduated and did not graduate). Is this probability zero? If yes, why?

Draw a tree diagram for three tosses of a coin. List all outcomes for this experiment in a sample space \(S\).

Many states have a lottery game, usually called a Pick-4, in which you pick a four-digit number such as 7359 . During the lottery drawing, there are four bins, each containing balls numbered 0 through 9\. One ball is drawn from each bin to form the four-digit winning number. a. You purchase one ticket with one four-digit number. What is the probability that you will win this lottery game? b. There are many variations of this game. The primary variation allows you to win if the four digits in your number are selected in any order as long as they are the same four digits as obtained by the lottery agency. For example, if you pick four digits making the number 1265, then you will win if \(1265,2615,5216,6521\), and so forth, are drawn. The variations of the lottery game depend on how many unique digits are in your number. Consider the following four different versions of this game. i. All four digits are unique (e.g., 1234 ) ii. Exactly one of the digits appears twice (e.g., 1223 or 9095 ) iii. Two digits each appear twice (e.g., 2121 or 5588 ) iv. One digit appears three times (e.g., 3335 or 2722 ) Find the probability that you will win this lottery in each of these four situations.

The probability of a student getting an A grade in an economics class is \(.24\) and that of getting a B grade is \(.28\). What is the probability that a randomly selected student from this class will get an \(\mathrm{A}\) or a \(\mathrm{B}\) in this class? Explain why this probability is not equal to \(1.0\)
