Question

A bag has 1 orange marble, 4 blue marbles, 3 yellow marbles, and 1

black marble. You randomly pull a marble from the bag, put it back,
and then pull out another one.
What is the probability of getting a blue and then a blue? Write your
answer as a fraction.

Answer 1

4/9

Explanation:

you know how many marbles there are in the bag so you add the number which is 9 so this shkws it will be something out of 9 since that is the total so now there are 4 blue marbles so you will just have to 4/9 I think thats how I would go on doing it.
