## FAQs on Example Marbles Drawn: Probability Video Lecture - CSAT Preparation - UPSC

 1. What is the probability of drawing a blue marble from the bag?
Ans. The probability of drawing a blue marble from the bag can be calculated by dividing the number of blue marbles by the total number of marbles in the bag.
 2. How many marbles are there in the bag?
Ans. The number of marbles in the bag is not mentioned in the given article or exam. Therefore, we cannot determine the exact number of marbles in the bag based on the information provided.
 3. What is the probability of drawing a red or green marble from the bag?
Ans. To calculate the probability of drawing a red or green marble from the bag, we need to add the number of red marbles and green marbles, and then divide it by the total number of marbles in the bag.
 4. Are the marbles in the bag replaced after each draw?
Ans. The article does not mention whether the marbles are replaced after each draw. Therefore, we cannot determine if the marbles are replaced or not based on the information provided.
 5. If two marbles are drawn from the bag, what is the probability of drawing two blue marbles?
Ans. To calculate the probability of drawing two blue marbles, we need to multiply the probability of drawing a blue marble on the first draw by the probability of drawing a blue marble on the second draw. However, since the article does not provide the total number of marbles or the number of blue marbles, we cannot determine the exact probability.
