A steel cannonball that are manufactured follow roughly a normal distribution N - (85g, (6 g)). The steel cannonballs are packed into groups of "small", "normal", "large" by weight. So that we classify in to the class "large" all of the cannonballs that are over 90kilos, and 25% of the cannonballs are classified in to the class "small".
- How much of the cannonballs are classified as large?
- What is the threshold below which cannonballs are classified as small?
