Because 15 out of a total of 50 marbles are green,
15 out of 50
15/50
Simplify fraction (divide top and bottom by 5)
3/10
or, if you prefer percent,
30%

The chance that it is not green is every chance except the green ones.
Every chance minus green chance
50/50 - 15/50
35/50
Simplify fraction (divide top and bottom by 5)
7/10
or,
70%

Paraphrase:

There is a 30% chance to get a green marble and a 70% chance of not getting a green marble.
