1. Use the rbinom() function to create a vector of 10 random observations from the binomial distribution with n=100 and probability of success is equal to 0.4.
   1. Calculate the mean and standard deviation statistics for this vector of random draws using the mean() and sd() commands.
   2. How do these numbers compare the mean and standard deviation of the binomial distribution when and ? If they are different, why?
   3. Make a histogram of this vector using the hist() command.
