Final answer:

The probability of getting 2 red marbles is 36/121.

Step-by-step explanation:

To find the probability of getting 2 red marbles, we need to consider the probability of getting 1 red marble on the first draw and then another red marble on the second draw.

There are a total of 5 blue and 6 red marbles in the bag.

Since we are replacing the marble after each draw, the probability of getting a red marble on the first draw is 6/11.

Since we replaced the marble, there are still 5 blue and 6 red marbles in the bag.

Therefore, the probability of getting a red marble on the second draw is also 6/11.

To find the probability of both events happening, we multiply the probabilities together:

= (6/11) * (6/11)

= 36/121.

So, the probability of getting 2 red marbles is 36/121.
