Probability is a measure of how likely it is that an event will happen. It is expressed as a number between 0 and 1, where:
0: Indicates the event will never happen.
1: Indicates the event will always happen.
Example:
The probability of rolling a 6 on a standard six-sided die is 1/6 because there are six equally likely outcomes.
The probability of choosing a student at random from a class is also 1/6 because there are six students in the class.
The probability of it raining tomorrow is high, so the probability of going outside is also high.
Key points about probability:
Probability tells us how likely it is for an event to happen, not how certain it is.
Probability is used in many fields, including statistics, engineering, and game theory.
Different events have different probabilities.
The sum of the probabilities of all possible outcomes of an event is always 1.
Additional notes:
Probability is not the same as risk or certainty.
A high probability doesn't guarantee the event will happen; it just makes it more likely.
Probability is a continuous measure, meaning its values can be any real number between 0 and 1
