Applause man. I just filled my gaps with all your videos even recommending to my class mates. Thank you much Boss.

i needed this so much! when i started my horribly organized probability theory class i needed simple and clear explanations to all the terms that were thrown in . well i didn't get it then but luckily you exist ! wishing you all the best !

Great introduction. Fills in the gaps in a very straight forward manner using a simple example.

Please help-4. Bone density can be measured using a DEXA test. Bone density for a 25-year-old woman is normally-distributed with a mean of 956 g/cm2 and a standard deviation of 5.52 g/cm2. Let X be the bone density of a randomly selected 25-year-old woman in g/cm2.

But how do you plot the pdf in the first place, you said you 'll draw it first and then explain but never did. Thanks though

I have read that distance between two places is continuous variable, then why the P(continuous variable) is 0. Since distance between two places can be exact value.

I love your videos but I really wish you would have used a better microphone..

Question: If there is a 0% chance that a random single sample from a large population is exactly 1.73m, then how do i grow past it. to grow i must pass every number that is ahead of me. This means that at one point in my life, i am exactly 1.73m and therefore isnt there a chance that you can sample a person who is 1.73m. The chance is low, but possible. No?

Sir, can you help me how to get this answer? 👇

The probability that it is sunny in a day is 0.30 and the probability that a student wears a hat is 0.65. The probability that it is sunny or the student does not wear a hat is 0.46. If it is a sunny on a particular day, find the probability that the student does not wear hat.
Answer: 19/30
