3. A speaker is talking about the principle of charity, and suggests that a person who is truly charitable will offer money to someone in need unreservedly. He illustrates this by saying that one should open their wallet and hand money to another person without looking at how much money they are holding. Suppose this speaker had five bills in his wallet: two $20, one $10, and two $5. If he were to choose one bill at random to give away to the next person who asked him, what is the expected value of his handout?
