Question

There is a river whose average daily flow Q follows a normal distribution. The average flow is 800
cfs and the standard deviation is 1000 cfs. Determine the following:
(a) The probability that the flow observed on a given day exceeds 10,000 cfs. [10 points]
(b) The probability that the observed flow is between 5,000 and 7,000 cfs. [10 points]
(c) The value of the flow that has a probability of 1% of exceeding
