# Probability Questions and Answers

**Probability Questions with Solutions**

Here in this page you will get Probability based Practice Questions and Answers, with basic definition, concepts and practice examples. Go through this page to learn the concept of Probability.

**Formula of Probability:**

**Probability** is a way of understanding and quantifying how likely or unlikely something is to happen based on the information we have.

**Important points related to Solving Probability Questions:**

**Probability ranges from 0 to 1:**The probability of an event can never be less than 0 (impossible event) or greater than 1 (certain event).**Sample Event:**The sample space is the set of all possible outcomes of an experiment or random event.**Event:**An event is a subset of the sample space, representing a specific outcome or a combination of outcomes.- The total of the chances of all regular actions should be 1.
- If the action’s possibility is near to 1, the probabilities of an action to happen will be more.
- If the chances of the event is near to 0, the probabilities of an incident to happen will be lesser in number.
**Addition rule:**The probability of the union of two events A and B (A or B) is calculated by adding their individual probabilities and subtracting the probability of their intersection (A and B).**Multiplication rule:**The probability of the intersection of two independent events A and B (A and B) is calculated by multiplying their individual probabilities.
