a bag contains 6 blue marbles,3 green marbles, and 2 yellow marbles. Ava will select a marble from the bag without looking.What is the probability that she will select either a green or a yellow marble?
In total Ava has 11 marbles. 5 of them are either green or yellow, so the probability Ava would pick a green or yellow marble is 5/11. Hope this helps!
So you add up all the marbles which is 6+3+2 which is 11, you than add the green and yellow which is 3+2 which is 5 and then to write the finally answer you do 5/11
