1. Suppose that there is a white urn containing two white balls and one red ball and there is a red urn containing one white ball and three red balls. An experiment consists of selecting at random a ball from the white urn and then (without replacing the first ball) selecting at random a ball from the urn having the color of the first ball. Find the probability that the second ball is red?
2. A card is drawn from a 52-card deck. If the card is a face card (jack, queen, or king), we toss a coin. If the card is not a face card, we roll a die. Find the probability that we end the sequence with a "6" on the die. Find the probability that we end the sequence with a "head" on the coin?
