There are 2 bags, each containing red blocks and yellow blocks. Bag 1 contains 1 red block and 3 yellow blocks. Bag 2 contains 4 red blocks and 12 yellow blocks. Tom says he is more likely to pick a red block out of bag 2 than out of bag 1 because bag 2 has more red blocks than bag 1. Is this correct? Explain your reasoning.
