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

thats really confusing i was thinking the answer was c but idk
no its d
its 4/12 because there are 4 blue and 12 total so a 4 out of 12 chance then a kid takes the marble so now there is only 11 marbles total and 3 yellow so 3/11 and a 3 out of 11 chance now u cross multiply 4*3=12 and 11*12=132 so 12/132
