FAQ

Q: What is probability?
A: Probability refers to the likelihood or chance of an event occurring.

Q: How do you calculate probability?
A: Probability is calculated by dividing the number of desired outcomes by the total number of possible outcomes.

Q: What is the probability of an event that is certain to happen?
A: The probability of an event that is certain to happen is 1 (or 100%).

Q: What is the probability of an event that is impossible to happen?
A: The probability of an event that is impossible to happen is 0 (or 0%).

Q: What is the probability of an event that is equally likely to happen or not happen?
A: The probability of an event that is equally likely to happen or not happen is 0.5 (or 50%).

Q: What is the difference between independent and dependent events?
A: Independent events are not influenced by each other's outcomes, while dependent events are influenced by each other's outcomes.

Q: What is the probability of two independent events both occurring?
A: The probability of two independent events both occurring is the product of their individual probabilities.

Q: What is the probability of two dependent events both occurring?
A: The probability of two dependent events both occurring is the product of their individual probabilities, taking into account the influence of the first event on the second event.

Q: What is a sample space?
A: A sample space is the set of all possible outcomes of an experiment.

Q: What is an event?
A: An event is a specific outcome or set of outcomes within the sample space.
