Probability is a concept that allows us to quantify our beliefs or expectations about the likelihood of certain events occurring. It provides us with a way to express our understanding of chance and uncertainty.


When we engage in activities like gambling, we acknowledge that the outcomes are uncertain and cannot be predicted with certainty. These activities often involve random experiments or trials, such as tossing a coin or drawing a card from a deck. The result of each experiment is entirely unpredictable and is called an outcome.


In the context of probability, we are usually interested in specific sets of outcomes, which we refer to as events. An event can be something like getting heads when flipping a coin or drawing a red card from a deck. It represents a particular outcome or a combination of outcomes that we consider favorable or relevant.


To understand probability, we need to consider the sample space, which encompasses all possible outcomes of a random experiment. For example, when flipping a coin, the sample space consists of two possible outcomes: heads or tails. In the case of drawing a card from a deck, the sample space comprises all the cards in the deck.

Within the sample space, individual elements are known as sample points. In the coin-flipping example, the sample points are heads and tails. In the card-drawing example, each card in the deck represents a sample point.
