Probability denotes the possibility of the outcome of any random event. The meaning of this term is to check the extent to which any event is likely to happen. For example, when we flip a coinin the air,what is the possibility of getting a head? The answer to this question is based on the number of possible outcomes. Here the possibility is either ...
Statistics is the study of the collection, analysis, interpretation, presentation, and organization of data. It is a method of collecting and summarising the data. This has many applications from a small scale to large scale. Whether it is the study of the population of the country or its economy, stats are used for all such data analysis. Statisti...
There are various terms utilised in the probability and statistics concepts, Such as: 1. Random Experiment 2. Sample Sample 3. Random variables 4. Expected Value 5. Independence 6. Variance 7. Mean Let us discuss these terms one by one.
Probability Formulas: For two events A and B: Statistics Formulas: Some important formulas are listed below: Let x be an item given and n is the total number of items.
Here are some examples based on the concepts of statistics and probability to understand better. Students can practice more questions based on these solved examples to excel in the topic. Also, make use of the formulas given in this article in the above section to solve problems based on them. Example 1: Find the mean and mode of the following data...
Learn the basics of probability and statistics, two important concepts in maths, with definitions, terms, formulas and examples. Find out how to handle data, calculate probabilities, and apply various topics in Class 9, 10 and 11.
The analysis of events governed by probability is called statistics. View all of Khan Academy’s lessons and practice exercises on probability and statistics. The best example for understanding probability is flipping a coin: There are two possible outcomes—heads or tails. What’s the probability of the coin landing on Heads?

- Yes you can multiply probabilities with fractions that are equal to one. We usually want the fraction in the simpliest form though.
- Usually, the question concerning probability should specify if they want either fractions or percentages. Here on KA, you can tell if they're askin...
