Using R:

Write a function simulatePlanes() that takes in as input a number of days and a logical value determining whether you want tothe plot or not. If you do not want to see the plot, have it return a vector of simulated plane counts for each day. If you would like to see the plot, have it return a list, the first element of which is the vector of simulated plane counts for each day, and the second element of which is a histogram.
