We introduce the basics of probability density and mass functions and how they let us handle different kinds of random variables. Video by Ari Seff ( / ariseffai ) Princeton COS 302 Lecture 15, Part 2
Thank you for the very clear explanation! I never took a stats class, so online resources like this help me survive upper division CS and ME classes. Much needed for fluids labs and speech processing!
Very well explained. You're communications clarity is exceptional. You deserve more Subs ... if only the YT algorithm could select automatically for quality of content rather than existing quantity of traffic, you'd be on your way to orbit in this field.
4:37 Say if the p(X=4)=0.5 What is the interpretation of this exact statement? Could it be that the probability of x occurring arbitrarily close to 4 is 50%?
No, that's still a discrete distribution. It has a probability mass function rather than a density function. The Poisson and geometric distributions are both examples of discrete distributions over a countable set.

Thanks. This explanation was very clear, concise, and helpful.
Glad it was helpful!
Underrated channel
Very beautiful. Thank you.
Just brilliant.
Great explanation !

One query! When we have countable infinite values, would that be considered as continuous distribution/setting?
No, that's still a discrete distribution. It has a probability mass function rather than a density function. The Poisson and geometric distributions are both examples of discrete distributions over a countable set.
