Simulation Assignment $1.$ Write a code that simulates two independent exponential distri$-$

butions with parameters ${}_1=1$ and ${}_2=2,$ and returns the variable $Z=\frac{Y}{x}.$ Generate a lot

of samples of $Z($at least $10,000)$ and plot a histogram of the values of $Z.$ Plot this histogram

and the theoretical distribution found in problem $6$ of Homework $1$ in the same plot $($you might

need to normalize the histogram so that the two are on top of each other$).$
