Probability is a measure of the likelihood of an event occurring. It is expressed as a number between 0 and 1, where 0 represents impossibility and 1 represents certainty.
Probability is calculated by dividing the number of desired outcomes by the total number of possible outcomes. This can be expressed as a fraction, decimal, or percentage.
Theoretical probability is based on mathematical calculations and assumes that all outcomes are equally likely. Experimental probability is based on the results of actual experiments or real-life events.
Independent events are events that have no effect on each other. The outcome of one event does not influence the outcome of the other. Dependent events, on the other hand, are events where the outcome of one event does affect the outcome of the other.
Probability can be used in many areas of life, such as predicting weather patterns, making financial decisions, and conducting scientific experiments. It can also be used to make informed decisions and assess risks in everyday situations.
