Glaucoma is a disease of the eye that is manifested by high intraocular pressure. The distribution of intraocular pressure (IOP) in the general population is approximately normal with an average of 15 mm Hg and a variance of 9 mm Hg. If the appropriate range of intraocular pressure is considered between 15 mm Hg and 18 mm Hg, What is the probability that an individual from this population is NOT in this range? A. 1 B. 0.8413 C. 0.4413 D. 0.6587 E. 0.5587
