Probability is a measure of the likelihood that an event will occur. It is expressed as a number between 0 and 1, where 0 indicates impossibility and 1 indicates certainty.
Probability is the theoretical branch of mathematics that deals with the likelihood of events occurring. Statistics, on the other hand, is the application of mathematical methods to analyze and interpret data and make predictions about future events.
The two main types of probability are theoretical (or classical) probability and experimental (or empirical) probability. Theoretical probability is based on mathematical principles and assumes that all outcomes are equally likely. Experimental probability is based on actual observations and data.
A normal distribution is a bell-shaped curve that represents a set of data whose values are symmetrically distributed around the mean. It is commonly used in statistics to describe the distribution of real-world data.
Probability and statistics are used in a wide range of fields, including science, finance, engineering, and social sciences. They can be used to make predictions, analyze trends, and make informed decisions based on data. Some examples of applications include weather forecasting, risk analysis, and market research.
