The chance to pull a yellow is the same from the start
Because you add 1 to yellow and 1 to green. They are
9n marbles so 60% is yellow and 30% is green.10%
blue 4/8 50% ⅜ 37.5%⅛ 12.5% before added
marglles
After added marbles 5/10 4/10 1/10

Justify your answer:
Step 1:There are 16 green
marbles,7 yellow and 3 blue!!! 2
green and 1 yellow marbles are
added!!!
Step 3: We will use addition

Green’s chance
+
+
First there was 8 green marbles then he put 3 more in. There was 7 yellow
marbles then he put 1 more in it. Blue was never added. We need to figure
out how much yellow’s chance of getting picked is increased decreased or
stays the same

Jayden, Gracie, Aiden
Keenan places 16 green marbles, 7 yellow marbles and 3 blue marble in a bag.
Keenan then adds 1 green marble and 1 yellow marble to the bag.
Does the probability that Keenan will randomly choose a yellow marble increase, decrease or stay the same?
