1. The number of barrels of oil produced yearly by a specific oil well is normally distributed with
µ = 7500 barrels and σ = 1000. If the well owner has a yearly quota of 9750 barrels, what is the probability that the well's production will meet or exceed this quota?
2. Suppose that the lifetimes of a certain type of light bulb are normally distributed with µ = 1200 hours and σ = 160. Find the probability that a light bulb will burn out in less than 1000 hours.
