statistics binomial distribution

The data below clearly indicates the number of times a rain falls per week in Port Elizabeth & Uitenhage area Number of times rain falls/week 0 ri Rainfall chance 0.01 03 0.05 0.31 0.3 0.03 a. Display the data graphically b. Find the probability that the number of rainfalls in a given week is- Exactly two times P(05x52) P(at least three rainfalls per week) iv P(at most five rainfalls per week) P(x > 1) C. Hence find the mean , variance & the standard deviation
