Barbara has three boxes. She's a computer scientist, so she numbers her boxes starting with 0.• Box 0 contains 3 maroon balls and 7 gold balls.• Box 1 contains 3 maroon balls and 7 gold balls.• Box 2 contains 5 maroon balls and 1 gold balls.Suppose that Barbara selects a ball by first flipping two fair coins. If she gets 0 heads, she chooses box 0. If she gets 1 head,she choose box 1. If she gets 2 heads, she chooses box 2. Once she has selected a box, she draws one ball out of the box(each ball equally likely to be drawn).What is the probability that Barbara selects a gold ball?If Barbara selects a ball from Box 1, what is the probability that that ball will be gold?If Barbara selects a gold ball, what is the probability that it came from Box 1?
