I feel like 10 minutes of KhanAcademy is worth more than 2 hours of lecture

I learned this from my professor in the last few days and the concept made little sense to me, because he didn't fully elaborate as you do. Thank you for the stupendous clarity.

It's so clear! My professor takes days to describe it, using tons of definitions. This video is so good!

These Concepts work fine until you get University questions and nothing makes sense anymore.

Oh My God! I was struggling to get sample distribution for more than hours of explanations from different many videos. This video just a length of 7 minute
explains very precisely in a simple manner without any bombarding things. Just cant believe in 7 minutes, it's possible to explain sampling distribution

Why are we replacing the ball and taking? As in, in our population for the balls, we don't have 2 balls having the value 1 right? What is the need for replacement?
