This is a Poisson Distribution
Average over 3 months = 2
Average over 1 month = 2/3
Average over 2 months = 4/3 = λ
More than four heavy rainfalls means 5, 6, 7,…
P(5) = (e^-λ x λ^5)/5! = 0.009257
P(6) = 0.002057
P(7) = 0.000392
P(8) = 0.000065
P(9) = 0.000010
P(10) = 0.000001
P(more than 4 heavy storms) = 0.01178 (4sf)
