Answer:

Explanation:

Comment

There are 9 marbles all together.

  • 2 are green
  • 4 are red
  • 3 are blue

The important fact is that he draws 1 marble to begin with and does not replace it. That means that the next marble is out of 8.

Solution

First marble: Blue = 3/9 = 1/3

Second marble: Green 2/8 = 1/4

The probability of that happening is

P(blue,Green) = 1/3 * 1/4 = 1/12

Answer P(blue, green) = 1/12
