Probability is a branch of mathematics that deals with the likelihood of events happening. It is used to predict the chances of an event occurring. Here are the basic concepts of probability:

1. Experiment: An experiment is a procedure carried out to observe a possible outcome. For example, tossing a coin is an experiment.

2. Sample Space: The sample space of an experiment is the set of all possible outcomes. For example, the sample space of tossing a coin is {Head, Tail}.

3. Event: An event is a specific outcome or combination of outcomes of an experiment. For example, getting a head when a coin is tossed is an event.

4. Probability of an Event: The probability of an event is the measure of the chance that the event will occur as a result of an experiment. It is calculated by dividing the number of favorable outcomes by the total number of outcomes. For example, the probability of getting a head when a coin is tossed is 1/2.

5. Complementary Events: Two events are said to be complementary if the occurrence of one event means the other cannot happen. For example, getting a head and getting a tail when a coin is tossed are complementary events.

6. Independent and Dependent Events: Two events are independent if the occurrence of one does not affect the occurrence of the other. If the occurrence of one event does affect the occurrence of the other, then the events are dependent.

7. Mutually Exclusive Events: Two events are mutually exclusive if they cannot occur at the same time. For example, getting a head and getting a tail when a coin is tossed are mutually exclusive events.

8. Addition Rule: The probability that either of two events will occur is the sum of their individual probabilities minus the probability of them both occurring.

9. Multiplication Rule: The probability that both of two independent events will occur is the product of their individual probabilities.

These are the basic concepts of probability. Understanding these concepts will help you to solve probability problems.
