The answer is 15/121.
Since we have red AND blue, that means that both of these events occur, so we will use the multiplication rule and multiply these two probabilities:
- A probability of choosing a red marble: 3/11. (because there are 3 marbles out of total 11 marbles)
- A probability of choosing a blue marble after the red one: 5/11. (because there are 3 marbles out of total 11 marbles; there are 11 in total again because the first marble has been returned)
So, P(red and blue) is 3/11 * 5/11 = (3*5)/(11*11) = 15/121

Step-by-step explanation:
Find the area of the shaded region by subtracting the area of the small shape from the area of the larger shape. The result is the area of only the shaded region, instead of the entire large shape. In this example, the area of the circle is subtracted from the area of the larger rectangle.
