A game at the local annual Apple Festival has players reach into a covered tub to pull out an apple. In the tub are 10 red apples, 3 green apples, and 1 yellow apple. Let R be the event of drawing a red apple, G be the event of drawing a green apple, and Y be the event of drawing a yellow apple. If a player draws a green apple, then the player has the choice of taking a $2 prize or (leaving the green apple out) reaching back into the tub for a chance to draw the yellow apple (which gives a prize of $20). There is no prize for drawing a red apple. First, find P(Rc). What does this mean regarding winning a prize on the first draw? Then, if on the first draw Deion pulls out a green apple, then decides to make a second draw instead of taking the $2 prize, what is the probability Deion will win at least $2?

The table describes the distribution of a random sample S of 200 individuals, arranged by education level and income.
