Answer to Question 1

P(A ) = 0.27 + 0.13 + 0.02 = 0.42

Answer to Question 2

Inspect the data using either graphical tools or descriptive statistics. If the mean is quite a bit different from the median, there may be an outlier or outliers. We would want to examine the outlier to make sure that it was a legitimate value. If so, we should keep it in the data set. Otherwise we may want to remove it from the data set.
