The 60-year record shows that the annual maximum discharges for a river have a mean of 30,000 cfs, a standard deviation of 28,000 cfs, and a skewness coefficient of 3.15. If the annual maximum discharge can be described by the Extreme-value Type I distribution, what is the probability that the annual maximum discharge exceeds 100,000 cfs at least once in next 10 years? (Note: The sample size is 60. Conduct interpolation using exceedance probabilities or cumulative probabilities.)

Read the question carefully and give me right solution according to the question
The water balance is defined by the general hydrologic equation, which is basically a statement of the law of conservation of mass applied to the hydrologic cycle. In its simplest form, this equation reads I= O + AS. where l is total inflow. O is total outfiow and AS is change in storage. In a month of 30 days, a lake received an average inflow of 6 m^3/s from surface runoff. In that same period, outfilow from the lake had an average value of 6.5 m^3/s. Further, the lake received a rainfall of 145 mm. evaporation of 6.10 cm and seepage loss was 2.5 cm in that month. The average lake surface is 5000 ha. Compute for the change in water elevation in the lake at the end of that month in centimeters. If it is a LOSS, indicate this by preceding your answer with a negative sign. "
