Marcus is playing a carnival game where he must guess the color of a candy bean before he pulls it out of a hat. He gets five tries and will earn 3 points every time he guesses correctly. However, he will lose 1 point for an incorrect guess. If there are 4 red, 2 green, and 2 yellow candy beans in the hat and Marcus guesses red every time, how many points can he expect to earn?
