FAQs on Flashcard: Probability Video Lecture - Mathematics (Maths) Class 10

1. What is the definition of probability in statistics?
Ans. Probability is a measure of the likelihood that a particular event will occur, expressed as a number between 0 and 1, where 0 indicates impossibility and 1 indicates certainty. It can also be represented as a percentage.
2. How do you calculate the probability of an event?
Ans. The probability of an event can be calculated using the formula: P(A) = Number of favorable outcomes / Total number of possible outcomes. For example, if you have a six-sided die, the probability of rolling a three is 1/6.
3. What is the difference between independent and dependent events in probability?
Ans. Independent events are those whose outcomes do not affect each other. For example, flipping a coin and rolling a die are independent events. Dependent events, on the other hand, are those where the outcome of one event affects the probability of the other, such as drawing cards from a deck without replacement.
4. What are the different types of probability?
Ans. There are three main types of probability: theoretical probability, which is based on the reasoning behind probability (e.g., flipping a coin); experimental probability, which is based on actual experiments or trials; and subjective probability, which is based on personal judgment or estimation.
5. How can probability be used in real-life situations?
Ans. Probability can be applied in various real-life situations such as predicting weather forecasts, assessing risks in finance, making decisions in business, and even in games of chance like poker. It helps individuals and organizations to make informed decisions based on the likelihood of different outcomes.
