There is a bag filled with 5 blue and 6 red marbles. A marble is taken at random from the bag, the colour is noted and then it is replaced.
Another marble is taken at random.
What is the probability of getting 2 blues?

Hello! Thanks for asking your question.

Your question is:

There is a bag filled with 5 blue and 6 red marbles.

A marble is taken at random from the bag, the colour is noted and then it is replaced.

Another marble is taken at random.

What is the probability of getting 2 blues?

I believe the best possible answer is 6/11 because there are 11 marbles in total, and 6 of them are blue! The possibility of them being 2 in a row is 6/11.

Have a great day!
