Two events are independent if the occurrence of one does not affect the probability of the other occurring. The document provides examples of calculating probabilities of independent events, such as drawing marbles or cards from bags/decks where the items are replaced between drawings. It also includes examples of finding probabilities when events like being on time are independent, such as the probability of both a student and bus being on time.

12. 5. If the school bus is on time 8% of the time and you are on time 7% of the time, what is the probability that both you and the bus will be on time? 8% x 7% = .0056 = 0.56%

13. 7. If Perry is late for work 4% of the time and his boss is late 8% of the time, what is the probability that both will be late? 4% x 8% = .0032 = 0.32%

14. 9. If the mail is on time 98% of the time and Anthony pays his bills on time, 95% of the time, what is the probability that his bill payment will be received on time? 98% x 95% = .931 = 93.1%
