Suppose that at a famous aquarium, a docent found that 35 percent of elementary school children know the difference between dolphins and porpoises. If a docent has a tour group that has 9 elementary school children, what is the probability that at least two of the children know the difference between dolphins and porpoises? In a fantasy world, there is a region called Durotar, where about 68 percent of the denizens are orcs. If we happen upon a group of 7 denizens, what is the probability that the number of orcs is at least 2 and less than 5.8
