A random experiment is a process or action that leads to one or more outcomes, where the result cannot be predicted with certainty. For example, tossing a coin can result in either heads or tails, but before the toss, we cannot know which will occur. Each time the experiment is conducted, the outcome may vary, making it random. In statistics, random experiments are essential for understanding probability. They help in analyzing situations where outcomes are uncertain, such as rolling a die or drawing a card from a deck. By studying these experiments, we can calculate the likelihood of different outcomes and make informed decisions based on that information.
