Done for the Fall Semester

I've completely finished with all my classes for the fall.

I know I made an A in Digital Communications. That's the class where I made a 35 on my first test.

In the DSP class, I'm 99.9% sure I made an A.

In Random Processes I, I'm not sure. I wouldn't be surprised with an A or with a B. I did make above average on the first two tests, but the final that I just took was really tough. I don't think I made less than a B though.

So, the probability that I've got either a 4.0 or a 3.67 is close to 1. Therefore, my GPA is a discrete random variable. Pr(GPA=4.0)=p, Pr(GPA=3.67)=a-p, where a is close to 1. It is not actually 1 because it's theoretically possible that I made less than an A in DSP and/or less than a B in Random Processes I. This is a difficult problem to accurately model, because the probability values are just coming from how I "feel". I could say that I feel like I made an A with probabiltiy 1/2. That's all well and good, but I must then say that the probabilities of all the other grades (B,C,D,F) all must add up to 1/2. Of course, I could say that the probability of a B is also 1/2, but it's still theoretically possible that I made less, so I won't say that.


I'll never think about probability the same way again.
