Pedro has two options: he can enter raffle number 1, OR raffle number 2 along with raffle number 3. If Pedro chooses to enter raffle number 1, he can buy up to 100 raffle tickets. Each ticket has a 1 in 50 chance of getting selected. If Pedro chooses raffle number 2/raffle number 3, he will have a 1 in 10 chance for raffle 2, and a 1 in 20 chance for raffle 3. However, if Pedro chooses to enter raffle number 2/raffle number 3, he can only buy one ticket for raffle number 2, and one ticket for raffle number 3. Which option should Pedro choose--buying 100 tickets for raffle one, or buying one ticket for both raffle two and raffle 3?
