4/27

Hope this helps you!!

Answer 2

Answer:

4/27.

Step-by-step explanation:

There are a total of 9 marbles.

Prob( Choosing a red) = 4/9.

Prob(Choosing a blue) = 3/9.

So the required probability = 4/9 * 3/9

= 12/81

= 4/27.

Note: the probability values are multiplied because the 2 events are  independent.
