1-Probability and randomness are two concepts that are closely related and often used in conjunction with one another. Probability is the study of the likelihood of an event occurring, while randomness refers to the unpredictable nature of events. Together, these concepts help us understand the world around us and make predictions about future outcomes. 2-Probability is a fundamental concept in mathematics and is used to predict the likelihood of an event occurring. It is often expressed as a number between 0 and 1, with 0 indicating that an event is impossible and 1 indicating that an event is certain. Probability is used in a wide range of fields, including science, engineering, finance, and economics, to make predictions about future outcomes. 3-However, probability is not always a perfect predictor of future events. Randomness, or the unpredictable nature of events, can sometimes lead to unexpected and inaccurate outcomes . For example, a coin toss is often used as an example of randomness. While the probability of a coin landing heads or tails is 50%, the actual outcome of a coin toss is unpredictable and can vary from one toss to the next.
