The likelihood that a particular event will occur is called probability.
Probability is a branch of mathematics that deals with the chances of different outcomes occurring. It is a way of quantifying how likely or unlikely an event is to happen. For example, if you flip a coin, the probability of it landing on heads is 50%, because there are two possible outcomes (heads or tails) and one favorable outcome (heads).
Understanding probability can help in various real-life situations, such as predicting weather conditions, deciding in games of chance, or analyzing risk in investments. By assigning a value between 0 and 1 to the likelihood of an event occurring, where 0 means the event will not happen and 1 means it is certain to happen, we can better understand and manage uncertainties in decision-making.
