Welcome to the course material on Probability in General Mathematics. Probability is a fundamental concept in mathematics that deals with the likelihood of different events occurring. It is widely used in various fields such as statistics, economics, science, and everyday decisionmaking.
One of the key objectives of this topic is to enable you to solve simple problems in probability, including both addition and multiplication of probabilities. Understanding the basic principles of probability will not only enhance your mathematical skills but also sharpen your analytical thinking and decisionmaking abilities.
Probability is often represented as a number between 0 and 1, where 0 indicates impossibility and 1 indicates certainty. Events with a probability closer to 1 are more likely to occur, while those closer to 0 are less likely to occur.
When working with probability, it is essential to consider different outcomes and determine their chances of happening. This involves calculating the ratio of favorable outcomes to the total number of outcomes in the sample space.
One of the fundamental concepts in probability is experimental probability, which involves conducting experiments such as tossing a coin, rolling a dice, or picking a card. By observing the outcomes of these experiments, we can calculate the probability of specific events occurring.
Additionally, we will explore the principles of addition and multiplication of probabilities. In probability theory, the addition rule is used to find the probability of the union of two events, while the multiplication rule calculates the probability of the intersection of events.
In this course material, we will delve into topics such as frequency distribution, histograms, bar charts, and pie charts to visually represent data and probabilities. You will also learn about measures of central tendency, including mean, mode, and median, which help summarize data and provide insights into the average and most common values.
Furthermore, we will discuss cumulative frequency, range, mean deviation, variance, and standard deviation to understand the dispersion and variability of data. These statistical measures play a crucial role in analyzing data and making informed decisions based on probabilities.
Overall, mastering the concepts of probability will empower you to make informed predictions, analyze uncertain scenarios, and solve a wide range of problems in various fields. By the end of this course material, you will have a solid foundation in probability theory and the practical skills to apply it in realworld situations.
Congratulations on completing the lesson on Probability. Now that youve explored the key concepts and ideas, its time to put your knowledge to the test. This section offers a variety of practice questions designed to reinforce your understanding and help you gauge your grasp of the material.

(b) Find the probability of getting a total : (i) of 7 or 8 ; (ii) less than 4.
Question 1 Report
A bag contains 8 red balls and some white balls. If the probability of drawing a white ball is half of the probability of drawing a red ball then find the probability of drawing a red ball and a white ball if the balls are drawn without replacement.
