FAQs on 01 - Probability Based on Dice Experiment (Problem Solving) - Class 10 - Maths Video Lecture

1. What is probability based on a dice experiment?
Ans. Probability based on a dice experiment refers to the likelihood of obtaining a specific outcome or event when rolling a dice. It is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.
2. How do you calculate the probability of getting a specific number on a dice?
Ans. To calculate the probability of getting a specific number on a dice, you need to determine the number of favorable outcomes (i.e., the number of ways you can get the specific number) and divide it by the total number of possible outcomes (which is 6 for a standard dice). For example, if you want to find the probability of rolling a 4, the probability would be 1/6 since there is only one way to roll a 4 on a standard dice.
3. What is the probability of rolling an even number on a dice?
Ans. The probability of rolling an even number on a dice is calculated by determining the number of favorable outcomes, which in this case are the numbers 2, 4, and 6, and dividing it by the total number of possible outcomes (which is 6 for a standard dice). Therefore, the probability of rolling an even number is 3/6, which simplifies to 1/2.
4. What is the probability of rolling a number greater than 4 on a dice?
Ans. The probability of rolling a number greater than 4 on a dice is calculated by determining the number of favorable outcomes, which in this case is the number 5 and 6, and dividing it by the total number of possible outcomes (which is 6 for a standard dice). Therefore, the probability of rolling a number greater than 4 is 2/6, which simplifies to 1/3.
5. What is the probability of rolling a number less than or equal to 3 on a dice?
Ans. The probability of rolling a number less than or equal to 3 on a dice is calculated by determining the number of favorable outcomes, which in this case are the numbers 1, 2, and 3, and dividing it by the total number of possible outcomes (which is 6 for a standard dice). Therefore, the probability of rolling a number less than or equal to 3 is 3/6, which simplifies to 1/2.
