Peter is giving marbles to some children at a carnival. He has 5 red marbles, 4 blue marbles, and 3 yellow marbles. If Peter selects a marble randomly without looking, what is the probability that he will give a blue marble to the first child and then a yellow marble to the second child? 4 over 12 plus 3 over 12 is equal to 7 over 12 4 over 12 plus 3 over 11 is equal to 80 over 132 4 over 12 multiplied by 3 over 12 is equal to 12 over 144 4 over 12 multiplied by 3 over 11 is equal to 12 over 132

Vocaloid:

total marbles = 5 red + 4 blue + 3 yellow for giving a blue marble to the first child, the probability would be (blue/total) for giving a yellow marble to the second child, you must subtract 1 from the total (since one marble was already given away) and then find (yellow/new total) then, since it wants the probability of both events, multiply (blue/total)*(yellow/new total)
