Probability Definition
Probability is a measure of how likely it is for an event to occur. Many events cannot be predicted with complete certainty, but we can use probability to estimate their likelihood. Probability is the measure of the likelihood that an event will occur. It is quantified as a number between 0 and 1.
Probability of an Event
The probability of an event E, denoted by P(E), is a number between 0 and 1 that represents the likelihood of E occurring.
- If P(E) = 0, the event E is impossible.
- If P(E) = 1, the event E is certain to occur.
- If 0 < P(E) < 1, the event E is possible but not guaranteed.
Note: The sum of the probabilities of all events in a sample space is always equal to 1.
For example: When we toss a coin, there are only two possible outcomes: Heads (H) or Tails (T). However, if we toss two coins simultaneously, there will be four possible outcomes: (H, H), (H, T), (T, H), and (T, T).
Basic Concepts of Probability
Probability is defined as the likelihood of the occurrence of any event. Probability is expressed as a number between 0 and 1, where, 0 is the probability of an impossible event and 1 the probability of a sure event.
In this article on Basic Concepts of Probability, we will learn to predict Probability for an event likelihood and ranges from zero to one. It extends to distribution, which shows potential outcomes for random experiments. To find probability, determine the total possible outcomes.
