Concept of Probability

Probability is the measure of the likelihood or chance that a particular event will occur. The probability of an event is always a number between 0 and 1, where:

• 0 means the event will not occur.
• 1 means the event will definitely occur.
• Between 0 and 1, the probability represents the relative chance of the event happening.

Basic Probability Formula

The probability of an event E is given by the ratio of the number of favorable outcomes to the total number of possible outcomes in the sample space. It is written as:

Where:

• P(E) is the probability of event E,
• The total number of possible outcomes is the size of the sample space, ∣S∣.
