Along with the rainfall the number of rainy days play a vital role in every field of planning. With the help of the previous records the distribution of the rainfall data and the probabilities of the number of rainy days can be found and the future predicted. In this article we restrict ourselves to the Faisalabed district. The distribution of the rainfall data and the probabilities of the number of rainy days have been calculated for the three decades of each month along with the probabilities of a month.
