In "The Numbers Game," a state lottery, four numbers are drawn with replacement from an urn containing balls numbered \(0-9\), inclusive. Find the probability that a ticket holder has the indicated winning ticket. All four digits in exact order (the grand prize)

Short Answer

Expert verified
The probability that a ticket holder has the winning ticket for the grand prize in "The Numbers Game" state lottery is \(\frac{1}{10000}\).

Step by step solution

01

Total possible outcomes

To find the total number of possible outcomes, consider that there are 10 choices for each draw (digits from \(0 - 9\)) and each digit can be drawn independently with replacement. Therefore, the total number of possible outcomes is given by: \[10 \times 10 \times 10 \times 10 = 10^4\]
02

Winning combinations

For the grand prize, there is only one winning combination: having all four digits in exact order. Thus, there is only 1 winning combination.
03

Calculate the probability

Now we can calculate the probability of having the grand prize by dividing the number of winning combinations by the total number of possible outcomes: \[\text{Probability} = \frac{\text{number of winning combinations}}{\text{total possible outcomes}} = \frac{1}{10^4}\]
04

Simplify the probability

Finally, we simplify the probability: \[\text{Probability} = \frac{1}{10^4} = \frac{1}{10000}\] So, the probability that a ticket holder has the winning ticket for the grand prize in "The Numbers Game" state lottery is \(\dfrac{1}{10000}\).

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Combinatorics
Combinatorics is the branch of mathematics dealing with combinations of objects belonging to a finite set in accordance with certain constraints, such as those concerning the order of the elements. In the context of a state lottery, combinatorics plays a crucial role in determining the number of possible outcomes when numbers are drawn.

For instance, in 'The Numbers Game', the lottery involves drawing four numbers, with each draw having 10 possible outcomes (digits from 0 to 9). Since each number is drawn with replacement, the same number can be drawn in more than one position. The combinatorial calculation for the total number of outcomes uses the rule of the product, calculating all possible combinations of the digits. This is computed as:
\begin{align*}10 \times 10 \times 10 \times 10 & = 10^4. \text{align*}Hence, there are 10,000 (or \(10^4\)) possible combinations when four numbers are drawn with replacement from a set of 10 digits.
Finite Mathematics
Finite mathematics refers to areas of mathematics that deal with mathematical concepts and techniques which are typically used in real-world applications of business, industry, and other practical fields. It encompasses topics like algebra, graph theory, mathematical modeling, and especially probabilities, as seen in state lotteries.

When applying finite mathematics to 'The Numbers Game', it's important to understand that the lottery can be modeled using finite probabilistic methods. Since the game has a finite number of possible numerical outcomes, tools from finite math help to compute the probability of drawing a specific set of numbers. It is these finite properties that allow for a concrete calculation of winning odds, making the seemingly random lottery a system governed by mathematical principles.
Probability Calculation
Probability calculation is the process of determining the likelihood of a particular event occurring, often expressed as a fraction or percentage. The basic principle is to divide the number of ways the desired event can happen by the number of total possible outcomes.

In 'The Numbers Game', since there is only one grand prize-winning combination, the number of winning combinations is 1. As we learned from combinatorics that the total number of possible outcomes is \(10^4\), the probability of a ticket holder winning the grand prize is calculated by dividing the number of winning combinations (1) by the total number of possible outcomes (\(10^4\)). This gives:\begin{align*}\frac{1}{10^4} \end{align*} Therefore, the probability that a ticket holder has the winning ticket is \begin{align*}\frac{1}{10000}, or 0.01%. \end{align*} This calculation shows that the chances of winning the grand prize are quite low, which is typical for state lotteries.

Applicants for temporary office work at Carter Temporary Help Agency who have successfully completed a typing test are then placed in suitable positions by Nancy Dwyer and Darla Newberg. Employers who hire temporary help through the agency return a card indicating satisfaction or dissatisfaction with the work performance of those hired. From past experience it is known that \(80 \%\) of the employees placed by Nancy are rated as satisfactory, and \(70 \%\) of those placed by Darla are rated as satisfactory. Darla places \(55 \%\) of the temporary office help at the agency and Nancy the remaining \(45 \%\). If a Carter office worker is rated unsatisfactory, what is the probability that he or she was placed by Darla?

The chief loan officer of La Crosse Home Mortgage Company summarized the housing loans extended by the company in 2007 according to type and term of the loan. Her list shows that \(70 \%\) of the loans were fixed-rate mortgages \((F), 25 \%\) were adjustable-rate mortgages \((A)\), and \(5 \%\) belong to some other category \((O)\) (mostly second trust-deed loans and loans extended under the graduated payment plan). Of the fixed-rate mortgages, \(80 \%\) were 30 -yr loans and \(20 \%\) were 15 -yr loans; of the adjustable-rate mortgages, \(40 \%\) were 30 -yr loans and \(60 \%\) were 15 -yr loans; finally, of the other loans extended, \(30 \%\) were 20 -yr loans, \(60 \%\) were 10 -yr loans, and \(10 \%\) were for a term of 5 yr or less. a. Draw a tree diagram representing these data. b. What is the probability that a home loan extended by La Crosse has an adjustable rate and is for a term of 15 yr? c. What is the probability that a home loan cxtended by La Crosse is for a term of 15 yr?

The probabilitics that the three patients who are scheduled to receive kidney transplants at General Hospital will suffer rejection are \(\frac{1}{2}, \frac{1}{3}\) and \(\frac{1}{10}\). Assuming that the cvents (kidney rejection) are indcpendent, find the probability that a. At least one paticnt will suffer rejection. b. Exactly two patients will suffer rejection.

In a survey conducted in the fall 2006, 800 homeowners were asked about their expectations regarding the value of their home in the next few years; the results of the survey are summarized below: $$\begin{array}{lc} \hline \text { Expectations } & \text { Homeowners } \\ \hline \text { Decrease } & 48 \\ \hline \text { Stay the same } & 152 \\ \hline \text { Increase less than } 5 \% & 232 \\ \hline \text { Increase 5-10\% } & 240 \\ \hline \text { Increase more than 10\% } & 128 \\ \hline \end{array}$$ If a homeowner in the survey is chosen at random, what is the probability that he or she expected his or her home to a. Stay the same or decrease in value in the next few years? b. Increase \(5 \%\) or more in value in the next few years?

Refer to the following experiment: Urn A contains four white and six black balls. Urn B contains three white and five black balls. A ball is drawn from urn A and then transferred to urn B.
