Explanation / Answer

A) Probability = 12/60 There are only 60 balls and 12 possibilites of it being G sothat is how you get a. B) Probability = 30/60 Half of the numbers, out of 60, are going to be even so thatis how you get b. Independent: Yes, both events are independent because theirevents do not effect each other's outcomes. Drawing a speceficletter has nothing to do with drawing an even number or not. I hope that helps!
