3.a 33-year record of peak annual flow rates was subjected to a frequency analysis. the median value is defined as the mid value in the table of rank-ordered magnitudes estimate the following
1-the probability that,for a 2-years period, the peak flow rate will equal or exceed the median value in the second year but not in the first.
2-the probability that the peak flow rates in both of two consecutive years will equal or exceed the median value.
