A Bag of Marbles: Understanding Probability

Probability is a fundamental concept in mathematics that helps us understand the likelihood of events occurring. In this article, we will explore a problem involving a bag of marbles, which will help us understand the concept of probability and how to calculate it.

A bag contains eleven equally sized marbles, which are numbered from 1 to 11. Some of the marbles are shaded, and we need to find the probability that a marble chosen at random is either shaded or labeled with a multiple of 3.

To solve this problem, we need to understand the concept of probability. Probability is a measure of the likelihood of an event occurring. It is usually expressed as a fraction or a decimal value between 0 and 1. In this case, we need to find the probability that a marble chosen at random is either shaded or labeled with a multiple of 3.

Let's first identify the outcomes that satisfy the condition. We know that there are 11 marbles in total, and we need to find the number of marbles that are either shaded or labeled with a multiple of 3.

  • Shaded Marbles: Let's assume that there are 4 shaded marbles in the bag. This is a reasonable assumption, as there are 11 marbles in total, and we need to find the probability that a marble chosen at random is either shaded or labeled with a multiple of 3.
  • Marbles Labeled with a Multiple of 3: We know that the multiples of 3 between 1 and 11 are 3, 6, and 9. Therefore, there are 3 marbles that are labeled with a multiple of 3.

Now that we have identified the outcomes, we can calculate the probability. We know that there are 4 shaded marbles and 3 marbles labeled with a multiple of 3. Therefore, the total number of marbles that satisfy the condition is 4 + 3 = 7.

The probability of choosing a marble that is either shaded or labeled with a multiple of 3 is therefore 7/11.

In this article, we have explored a problem involving a bag of marbles and calculated the probability that a marble chosen at random is either shaded or labeled with a multiple of 3. We have identified the outcomes that satisfy the condition and calculated the probability using the formula for probability.

The correct answer is B. 311\frac{3}{11}.
