There is a bag filled with 4 blue and 5 red marbles. A marble is taken at random fròm the bag, the colour is noted and then is replaced. Another marble is taken at random. What is the probability of getting 2 blues

Hi there!

1/6

Explanation:

The first probability of getting blue is 4 out of the total marbles so 4/9.

The second time there are only 3 blue marbles out of 8 now so 3/8.

So the answer is 4/9X3/8

which equals 12/72 or 1/6

Hope this helps!
