Question

5 green marbles 5 red marbles 10 yellow marbles

Answer 1

Answer:

5/19

Step-by-step explanation:

Marbles=20

So the probability of choosing not yellow is 10/20=1/2.  

Marbles are not replaced.

The total number is 19

The probability of choosing yellow is 10/19

So the final answer is (1/2)*(10/19)=5/19.
