Answer 1

`\large\boxed{(50)/(363)\approx1.4}`

Explanation:

We have

10 + 5 + 15 + 3 = 33 marables

The probability of drawing of green marable is:

`(15)/(33)=(15:3)/(33:3)=(5)/(11)`

The probability of drawing of blue marable is:

`(5)/(33)`

The probability of drawing of green and blue marables is:

`(5)/(11)\cdot(5)/(33)+(5)/(33)\cdot(5)/(11)=(25)/(363)+(25)/(363)=(50)/(363)\approx0.14`
