Probability is a measure of the likelihood that a certain event will occur. It is typically expressed as a number between 0 and 1, where 0 represents impossibility and 1 represents certainty.
The probability of an event is calculated by dividing the number of favorable outcomes by the total number of possible outcomes. For example, if you roll a six-sided die, the probability of rolling a 3 would be 1/6 because there is only one favorable outcome out of six possible outcomes.
Conditional probability is the probability of an event occurring given that another event has already occurred. It is calculated by dividing the probability of both events occurring by the probability of the first event occurring.
Independent events are events where the outcome of one event does not affect the outcome of the other event. Dependent events are events where the outcome of one event does affect the outcome of the other event.
Probability is used in many areas of life, including weather forecasting, risk assessment, and sports analytics. It can also be used in decision making, such as choosing the best route to take when driving based on the probability of encountering traffic.
