Options: 

1.) Normal Distribution 

2.) Normal Approximation to the binomal distribution

3.) Exponential distribution

4.) Lognormal Distribution

5.) Binomial Distribution

6.) Geometric Distribution

7.) Negative Binomial Distribution

8.) Hypergeometric Distribution

9.) Poisson Distribution 

1) Choose the distribution
In Chapter 5, the calculations themselves aren't too tricky - often the hard part is simply
determining which distribution to use! For the following problems, write the name of the
distribution you would use in the box (no need to solve).
