A, B, C, D is not the sample space I used in my code. You remember that?
My sample space was: 25, 50, 60, 25. We'll call this sample space 1.
You remember that? Or do I need to quote myself? It sure the heck was not A, B, C, D.
Now when you used the unique function you changed that sample space to: 25, 50, 60. We'll call this sample space 2.
So when I ran the sample command it sampled from sample space 1.
When you ran the sample command it sampled from sample space 2.
That is what happened, and it is in black and white.
Now the question of interest is: Multiple Choice: If you choose an answer to this question at random, what is the chance you will be correct?
A) 25%
B) 50%
C) 60%
D) 25%
It has a sample space of: 25, 50, 60, 25. Now wait, that looks a lot like my sample space, sample space 1. While sample space 2, your sample space, is missing a value. Hmm... that can't be, as the random event for the question is for the sample space of the question. How could this possibly happen? Oh I know, you are doing it wrong.
Why don't you run the code correctly this time, with the correct sample space and stop trying to save face. I am sorry, but this is just beyond sad.
