The daily water consumption for an Ohio community is normally distributed with a mean consumption of 829,945 gallons and a standard deviation of 87,519 gallons. The community water system will experience a noticeable drop in water pressure when the daily water consumption exceeds 967,099 gallons. What is the probability of experiencing such a drop in water pressure? (Round your answer to 4 decimal places. Round Z-scores to 2 decimal places.)
