The demand for water use in Laguna in 2012 hit a low of about 188 million gallons per day. Water use in the rainy season is normally distributed with a mean of 200 million gallons per day and a standard deviation of 33 million gallons per day. City reservoirs have a combined storage capacity of nearly 250 million gallons. a. What is the probability that a day requires more water than is stored in city reservoirs? Ans = Blank 1 b. What reservoirs capacity is needed so that the probability that it is exceeded is at most 5%? Ans = Blank 2 million gallons
