## FAQs on Class 10 Mathematics - Probability Formula Explained With Ball And Card Experiment Video Lecture - Probability For Beginners - Mathematics and Statistics

 1. What is the probability formula for a ball and card experiment? Ans. The probability formula for a ball and card experiment is the number of favorable outcomes divided by the total number of possible outcomes. It can be expressed as P(A) = n(A)/n(S), where P(A) is the probability of event A, n(A) is the number of favorable outcomes for event A, and n(S) is the total number of possible outcomes.
 2. How do you calculate the probability in a ball and card experiment? Ans. To calculate the probability in a ball and card experiment, you need to determine the number of favorable outcomes and the total number of possible outcomes. Then, divide the number of favorable outcomes by the total number of possible outcomes. The resulting quotient is the probability of the event occurring.
 3. Can you explain the concept of favorable outcomes in a ball and card experiment? Ans. Favorable outcomes in a ball and card experiment refer to the outcomes that meet the desired condition or event. For example, if you are drawing a card from a deck of 52 cards and you want to draw a red card, the favorable outcomes would be the number of red cards in the deck. These favorable outcomes are used to calculate the probability of the event occurring.
 4. What is the importance of understanding probability in mathematics? Ans. Understanding probability in mathematics is crucial as it helps in making informed decisions based on the likelihood of events occurring. Probability allows us to analyze uncertainties, predict outcomes, and determine the chances of an event happening. It has applications in various fields such as statistics, finance, science, and engineering.
 5. Can you give an example of a ball and card experiment to explain the probability formula? Ans. Sure! Let's consider an example where we have a bag containing 4 red balls and 6 blue balls. If we randomly select a ball from the bag, what is the probability of choosing a red ball? In this case, the number of favorable outcomes is 4 (as there are 4 red balls), and the total number of possible outcomes is 10 (as there are 4 red balls + 6 blue balls). Therefore, the probability of choosing a red ball would be 4/10, which simplifies to 2/5 or 0.4.
