2. Find the MLE for the discrete RV given in problem 5 of HW2 (using the particular data indicated in that problem). Then, explain why your answer for the MLE cannot be surprising (like it was on HW2). You should also draw a picture of the likelihood and log-likelihood (on the same axes) in Desmos and copy your Desmos inputs and picture into your solutions. Thinlk carefully about the domain of this graph x=1 5. Suppose a discrete RV is...
