FAQs on Examples: Independent Events Video Lecture - Mathematics (Maths) Class 12 - JEE

1. What are independent events in probability?
Ans. In probability, independent events are events that do not affect each other's outcome. The probability of one event occurring does not change based on the occurrence or non-occurrence of the other event.
2. How do you determine if two events are independent?
Ans. Two events are considered independent if the probability of both events occurring is equal to the product of their individual probabilities. Mathematically, if P(A) and P(B) are the probabilities of events A and B, then they are independent if P(A and B) = P(A) * P(B).
3. Can two mutually exclusive events be independent as well?
Ans. No, two mutually exclusive events cannot be independent. If two events are mutually exclusive, it means that the occurrence of one event excludes the possibility of the other event happening. In such cases, the probability of both events occurring simultaneously is always zero, making them dependent.
4. Are coin tosses independent events?
Ans. Yes, coin tosses are considered independent events. The outcome of each coin toss (head or tail) does not depend on the outcome of the previous or future tosses. Each toss has a 50% chance of resulting in either head or tail, regardless of previous outcomes.
5. How does understanding independent events help in calculating probabilities?
Ans. Understanding independent events is crucial in calculating probabilities as it allows us to determine the probability of multiple events occurring together. By multiplying the individual probabilities of independent events, we can find the probability of their joint occurrence. This concept is fundamental in various areas such as statistics, gambling, and risk analysis.
