Sir thank you very much for opening my understanding in this part of probability functions. The examples are loud and clear and much easier to follow through. You have really saved my life because tomorrow I will be writing my exams in statistics and probability.

cheers sir, it's been three years and this still works!

[@yalmazkhan4773]

good one sir, you have explained this concept very well

[@lanomusambazi8654]

Guide me also on how to find variance and standard deviation for discrete random variables. Then guide me again on how to find continuous random variables. I really want to understand the difference between these two random variables. I thank you sir once again. I wish you well in your life endeavours.
