Eleisha's Segment 2: Bayes
1. If the knight had captured a Gnome instead of a Troll, what would his chances be of crossing safely?
2. Suppose that we have two identical boxes, A and B. A contains 5 red balls and 3 blue balls. B contains 2 red balls and 4 blue balls. A box is selected at random and exactly one ball is drawn from the box. What is the probability that it is blue? If it is blue, what is the probability that it came from box B?
