A certain manufacturing process produces light bulbs whose life length (in hours) is a r.v. X distributed as Normal with μ = 2000 and σ = 200. A light bulb is supposed to be defective if its lifetime is less than 1800. If 25 light bulbs are tested, what is the probability that at most 15 of them are defective?
