A person with type AB blood can donate red blood cells to people with the same blood type. About 12% of the US population has type AB blood. University High held a blood drive where 50 students donated blood. Part A: What is the probability that exactly 8 of the students had type AB blood? (5 points)

Part B: What is the probability that at least 8 of the students had type AB blood? (5 points)

On traditional maps, earth is represented in a flat plane, or by euclidean geometry. however, a globe is a more accurate model that comes from elliptical geometry.how does a globe represent the fact that there are no parallel lines in elliptical geometry? the equator is not parallel to any other latitudinal lines. the north and south poles are never connected by a geodesic. the geodesics connecting the north and south poles never intersect. the geodesics connecting the north and south poles intersect at both of the poles.
