Robin is giving toy cars to some children at a carnival. He has 2 black toy cars, 7 blue toy cars, and 3 yellow toy cars. If Robin selects a toy car randomly without looking, what is the probability that he will give a yellow toy car to the first child and then a blue toy car to the second child?

3 over 12 multiplied by 7 over 11 is equal to 21 over 132
3 over 12 multiplied by 7 over 12 is equal to 21 over 144
3 over 12 plus 7 over 11 is equal to 117 over 132
3 over 12 plus 7 over 12 is equal to 10 over 12
