Answer 4

Probability is a chance game. You have to find your clues and understand them.
The jar contains 13 yellow and 10 green. That means that 13+10 = 23 total marbles are in your jar.
If a marble is picked randomly, then you have a chance to get either a yellow or a green marble.
If there are 13 yellow out of 23 marbles then the chances of getting a yellow is 13/23, similarly there are 10 green out of 23 therefore the chances of getting a green is 10/23.
If you get a green marble, then you don't get a yellow marble, and if you get a yellow marble, you don't get a green.

The chances of getting a green P(Green) = P(Not yellow) = 10/23
