Final answer:
The subject of this question is Mathematics, specifically probability and random variables. The question is asking for the probability of drawing a certain combination of marbles without replacement from an urn. To calculate the probability of drawing a specific combination of marbles, we can use principles of probability, such as the multiplication rule.
Step-by-step explanation:
The subject of this question is Mathematics, specifically probability and random variables.
The question is asking for the probability of drawing a certain combination of marbles without replacement from an urn. In this case, we are given that there are 3 red marbles and 8 blue marbles in the urn.
To calculate the probability of drawing a specific combination of marbles, we can use principles of probability, such as the multiplication rule. For example, if we want to calculate the probability of drawing 2 red marbles, we can multiply the probability of drawing the first red marble (3/11) by the probability of drawing the second red marble (2/10).
