() Examine the charts on this worksheet. Then change the probability of success to 0.2 (i.e., change the cell D2 from 0.5 to 0.2) and examine the charts. Then change the probability (i.e. cell D2) to 0.8. Briefly describe how the shape of the charts changed when you changed the probability of success from 0.5 to 0.2 and 0.8 (use the words, symmetry and skewness)
