Sam And Richard Are Playing Scrabble. The Probability Of Picking The Letter N From A Bag Of Letters Is 0.07.Which Of The Following Describes The Likelihood Of Picking The Letter N?A. Likely B. Neither Unlikely Nor Likely C. Unlikely
Introduction
Probability is a fundamental concept in mathematics that helps us understand the likelihood of events occurring. In everyday life, we encounter probability in various forms, from games of chance to real-world applications. In this article, we will explore the concept of probability using a simple example from a popular board game, Scrabble.
The Scrabble Example
Sam and Richard are playing Scrabble, a popular board game that involves creating words from letter tiles. The game requires strategic thinking and a good understanding of language. In this example, we are interested in finding the likelihood of picking the letter N from a bag of letters.
The Probability of Picking the Letter N
The probability of picking the letter N from a bag of letters is given as 0.07. This means that out of a total of 100 possible outcomes (i.e., 100 letters in the bag), there is a 7% chance of picking the letter N.
Interpreting the Probability
To understand the likelihood of picking the letter N, we need to interpret the probability value. A probability of 0.07 is relatively low, indicating that the event is unlikely to occur.
Likelihood of Picking the Letter N
So, which of the following describes the likelihood of picking the letter N?
- A. likely: This option is incorrect because a probability of 0.07 is not high enough to be considered likely.
- B. neither unlikely nor likely: This option is also incorrect because a probability of 0.07 is clearly on the side of being unlikely.
- C. unlikely: This option is correct because a probability of 0.07 indicates that the event is unlikely to occur.
Conclusion
In conclusion, the probability of picking the letter N from a bag of letters is 0.07, which is relatively low. Therefore, the likelihood of picking the letter N is unlikely. This example illustrates the importance of understanding probability in everyday life, from games of chance to real-world applications.
Understanding Probability in Real-Life Scenarios
Probability is a fundamental concept in mathematics that has numerous real-life applications. In addition to games of chance, probability is used in fields such as medicine, finance, and engineering. Understanding probability can help us make informed decisions and navigate uncertain situations.
Real-Life Examples of Probability
- Medical Diagnosis: In medicine, probability is used to diagnose diseases. For example, a doctor may use probability to determine the likelihood of a patient having a particular disease based on symptoms and test results.
- Financial Risk Management: In finance, probability is used to manage risk. For example, an investor may use probability to determine the likelihood of a stock price increasing or decreasing based on historical data and market trends.
- Engineering: In engineering, probability is used to design and optimize systems. For example, an engineer may use probability to determine the likelihood of a bridge collapsing based on factors such as material strength and load capacity.
Conclusion
In conclusion, probability is a fundamental concept in mathematics that has numerous real-life applications. Understanding probability can help us make informed decisions and navigate uncertain situations. The example of picking the letter N from a bag of letters illustrates the importance of understanding probability in everyday life.

Frequently Asked Questions (FAQs) About Probability =====================================================
Introduction
Probability is a fundamental concept in mathematics that helps us understand the likelihood of events occurring. In this article, we will answer some frequently asked questions about probability to help you better understand this concept.
Q: What is probability?
A: Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1 that represents the chance of an event happening.
Q: How is probability calculated?
A: Probability is calculated by dividing the number of favorable outcomes by the total number of possible outcomes. For example, if you have a bag of 10 marbles, 3 of which are red, the probability of drawing a red marble is 3/10 or 0.3.
Q: What is the difference between probability and likelihood?
A: Probability and likelihood are often used interchangeably, but they have slightly different meanings. Probability is a mathematical measure of the likelihood of an event occurring, while likelihood is a more subjective measure of how likely an event seems to be.
Q: What is the probability of an event that is certain to occur?
A: The probability of an event that is certain to occur is 1. This means that the event will definitely happen.
Q: What is the probability of an event that is impossible to occur?
A: The probability of an event that is impossible to occur is 0. This means that the event will never happen.
Q: Can probability be greater than 1?
A: No, probability cannot be greater than 1. Probability is a measure of the likelihood of an event occurring, and it must be a number between 0 and 1.
Q: Can probability be less than 0?
A: No, probability cannot be less than 0. Probability is a measure of the likelihood of an event occurring, and it must be a number between 0 and 1.
Q: What is the relationship between probability and chance?
A: Probability and chance are related but not the same thing. Probability is a mathematical measure of the likelihood of an event occurring, while chance is a more general term that refers to the possibility of an event happening.
Q: Can probability be used to predict the future?
A: Yes, probability can be used to predict the future. By analyzing data and using statistical models, we can estimate the likelihood of future events occurring.
Q: What are some common applications of probability?
A: Probability has many applications in fields such as medicine, finance, engineering, and insurance. It is used to make predictions, estimate risks, and make informed decisions.
Conclusion
In conclusion, probability is a fundamental concept in mathematics that helps us understand the likelihood of events occurring. By answering some frequently asked questions about probability, we hope to have provided you with a better understanding of this concept and its many applications.
