3) A box contains 4 yellow marbles, 2 blue marbles, and 3 red marbles. If a marble is drawn randomly from the box, but the marble drawn is replaced. What is the probability of drawing 2 yellow marbles and 1 red
marble?​

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!
