FAQs on Examples: Probability Part 1 Video Lecture - Class 9

1. What is probability and how is it calculated?
Ans. Probability is a mathematical concept that measures the likelihood of an event occurring. It is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.
2. How can probability be expressed?
Ans. Probability can be expressed as a fraction, decimal, or percentage. For example, if the probability of an event is 3/5, it can also be expressed as 0.6 or 60%.
3. What is the difference between experimental probability and theoretical probability?
Ans. Experimental probability is based on actual outcomes from conducting an experiment or observation, while theoretical probability is based on mathematical calculations and assumptions. Experimental probability relies on collecting data, while theoretical probability is determined through mathematical reasoning.
4. What is the probability of an event that is certain to happen?
Ans. An event that is certain to happen has a probability of 1. This means that the event will definitely occur.
5. Can the probability of an event be greater than 1?
Ans. No, the probability of an event cannot be greater than 1. Probability is always a value between 0 and 1, inclusive. A probability greater than 1 would imply that the event is certain to occur multiple times, which is not possible.
