The annual rainfall (accumulated generally during the winter and spring) of each year in Orange County, California, is a Gaussian random variable with a mean of 17 cm. and a standard deviation of 3.5 cm.; i.e., N(17, 3.5). Suppose the current water policy of the county is such that if the annual rainfall is less than 8.5 cm. for a given year, water rationing will be required during the summer and fall of that year. Then the probability of water rationing in Orange County in any given year is 0.7600 .a 0.0667 .b 0.9967 .C 0 9976 d O O
