Hey buddy I am here to help!
yellow marbles = 4
blue marbles = 2
red marbles = 3
total marbles = 9
1 random marbles taken off probability left = 8/9
1 random marble taken off probability = 1/9
marble if replaced = + 1
if one marble if replaced then = 8/9 + 1/9 = 9/9 that means total marbles r 9
yellow marbles drawn off = 2
so... 4 - 2 = 2 marbles left
red marbles taken off = 1
so... 3 -1 = 2 marbles left
probability/answer = 3/9 = 1/3
Hope it helps!
