Any time a die is rolled or a coin is flipped, probability comes into play, determining the outcome of the roll or the flip. Studying probability enables you to better understand this fundamental concept of everyday life. Intricately connected with probability, statistics is the process of collecting, arranging, and analyzing data involved with events. Probability and statistics are generally studied together, teaching you skills you can apply to many different areas of life, both professional and personal. A probability and statistics course will include subtopics such as arithmetic mean, distribution, analytics, and variance.
Probability involves predicting the outcome of specific events based on the possible outcomes.
Khan Academy offers a wealth of lessons, quizzes, and tests that can help you learn about and master probability and statistics.
Learning about statistics and probability allows you to better apply critical reasoning to your planning and decisions.

In statistics, plotting out how common something is or how often it happens will often produce a bell-shaped curve known as a normal curve or bell curve.
Standard Deviation Explained (video)
Standard deviation is a measure of how spread out the data is on a normal curve: If the standard deviation is smaller, that means that most of the results are clustered around the mean result.
Understanding these concepts is key to being successful at calculating statistics.
It might seem like statistics is a subject about dull math calculations, but when you start applying these ideas to real life, you can end up with some interesting puzzles with surprising results.
This activity takes you through the process of determining probabilities of mutually inclusive events using an algorithm.
