literally mate, my lecturer labours through this shit in 4 lectures, going through the proofs of everything, making it seem impossible and make me not want to learn it, you do it in 13 minutes and i understand it perfectly thankyou

The most advantage I take from your video is you use the most simple example to interpret the idea. Excellent !

Thanks for the helpful video! I think there is a mistake at 9:28 though; for Py(y) should it be (xi, y) not (xi, yj)?

So what is the actual answer for the marginal PMFs? Is it 7/24 + 5/12 + 7/24 for pY(y)?

At 16th sec, you were telling if...X is discrete...instead of continuous.

yeah, I had trouble making that out, sounded the same each time.

I cant understand what you are saying. When you say, "X is a single random variable, For example if x is ..... random variable You usually consider PMF. But if x is a ....... variable you usually consider PDF. Can you tell me the words in between or give me an exact sentence? Thank you P.S. Thanks for the video

Not clear. I cannot understand what you are saying about PMF & PDF at the very beginning of the video. Sounds like you are saying "I call PMF Discrete, but when considering PDF, I call Discrete?????" Please clarify.

Speak slower that will solve alot of things. I almost refused to continue with this video if you had not explained the "if x is a discrete..." part since i couldnt understand what you were saying
