Answer:
a) 1/4
b) green marbles
Step-by-step explanation:
since there are 20 marbles in total and 5 blue marbles, you simply need to do 5/20 and simplify it down which would be 1/4.
the green marbles are more likely to be drawn as there are more of them meaning there is a higher probability of picking a green marble.
hope this helps :)
