Q38

The standard normal cumulative probability function (probability from - to xn) can be approximated as F ( x_ n ) = 11 + exp ( - 1.7255 x_ n | x_ n |^0.12 ) where xn = standard normal deviate. If mean and standard deviation of annual precipitation are 102 cm and 27 cm respectively, the probability that the annual precipitation will be between 90 cm and 102cm is
