From the help of following image, show every formula used for each step in an excel sheet

 
3. Suppose the number of typographical errors on a page of a textbook has a Poisson distribution with average A = ½. Create the chart for the distribution and the cumulative distribution. Experiment to see how many scores you need to include. (Keep 4 decimal places for the values of the probabilities.) Draw the 2 graphs. Use the charts to determine the following probabilities: a) Exactly 2 errors. b) Fewer than 2 errors. c) At least 1 error.
