Probability | Chapter 15 | Class 10th | Quick Revision (22-23) | NCERT | Maths
Dear students, In this chapter we will learn about Probability. Below ⬇️ are the tutorial notes and videos. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one. Probability has been introduced in Maths to predict how likely events are to happen. Probability Definition in Math Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e. how likely they are to happen, using it. Probability can range in from 0 to 1, where 0 means the event to be an impossible one and 1 indicates a certain event.. The probability of all the events in a sample space adds up to 1. For example, when we toss a coin, either we get Head OR Tail, only two possible outcomes are possible (H, T). But if we toss two coins in the air, there could be three possibilities of events to occur, such as both th
