Answer:
Step-by-step explanation:
30% is the likelihood of picking a purple marble because 20% of 25 is 5 and 50% of 25 is 12.5 which leaves 7.5 marbles left (purple) and 7.5/25 = .30 which you multiply by 100 to get a percentage of 30
you are less likely to pick a purple marble than a green marble, but you have the least chance of picking a yellow marble
