Sir plz start any topic with basic lavel and said all topic significant and real life example?? so we will understand easyly.Plz relate physics with real life . Sir plz don't underestimate my opinion.
Sir ji fumble karte ho aap thoda other than that u are tooo gooood
Sarey formula milkar koi ek super formula hain Kya jo sure bata dein???
Shares market main Kya probability for sure formula hain????
If 75% of all purchases at a certain store is made with a credit card and X is the number among the ten randomly selected purchases made with credit card. Then find P(μ- 2σ< x < µ +2σ) where is µ the mean and σ is the standard deviation of the distribution
Hello please ye question explain krdi jiya
Thank you for explaining so nicely.I also wanted to say that around 20:40 ,P(x>=1.5) !=F(1.5).Actually it should be 1-F(1.5).(CORRECTION)
Thank u bhai💛💛
Yeah thnx someone said it
Bro, Can u explain to me why and what is the next step.
Can u please elaborate??
@@rakeshranjanprabhat9218 P(x>=1.5)=1-P(x

DESERVES MILLIONS OF VIEWS
Yes 👍 videos are very good
Sir please thoda slow padaya kro aap hume pada rahe h na ki khud pad rahe h
you are explaining perfectly sir!!!!keep helping us and stay safe!!!!!!
You reminded me of my favourite math lecturer sir. Thank you!! 🙏
Thank you for explaining such nicely. Your videos are really helpful for understanding a concept .
Thank you sir for your contributions, I will be grateful forever 🙏. You are helping me shape my future and I can't thank you enough.
Probably the best video so far on random variables . THANKS SIR
thank you so much sir for explaining on this level. we are greatful.
Sir, at 20:29 direct putting the value of x(let 1.5) in commulative distribution function will give the the value of P(x=1.5) and Thank you so much for this nice content.
I guess it should have been 1-P(x
Correct
thanks i got confused here , bcz i try to calculate the value as sir said but i am not getting 0.125 as answer.
Exactly
Helped me to clear my concepts and doubts. Thank You
Thank you Sir. Your classes are very interesting. 😊🙏🙏🙏

kaash ye video do saal pehle upload huyi hoti, mere ek backlog km hote😂😂
Bhai 2 year ago hi hai yeh
@Indian viewer nahi bhai, woh toh 9 months pehele comment kiya hai
Bhai is baar meri hai backlog ki exam 6 taarikh se 😂😂😂
Mere toh ekdm time pe uploaded h firbi padhne ka mann na karne ki wajah se nhi ho pa rha h😭😭😭
Bhai jaypee se hai kya??😢😢
Sir, at 20:40 for calculating P(X>=1.5), which is 1 - P(X
👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻
Thank you was confused. :-)
Yhi hota h jab teachers ko khud ko kuch ata na ho or book se dekh dekh k bol rhe ho
@Daredevil no
bhai ye x>2 keliye 20:40 mein integration kerne per value 1 nhi aarhi plz help
In my college , even teachers are not able to clearify our concepts, Thank you , G.P. sir ...
Sir I have question
18:19 time for ( x >2 ) we have take from -infinite to +infinite or 2 to +infinite
Cause (x
it should be 2 to infinity. It will become zero
thanks sir for explaining so well ..
but attention everyone .. i think at 20:40 there i think sir missed a point that P(x>=1.5) will be equal to {1-P(x
nope !!!!
i calculated it and , integration from 1.5 to 2 = 0.125.
You're best teacher I've ever come across
Sir 💖Your style of explanation is Awesome 👏👏👏
very knowledgeable person ! respect from my side
Thank you so much Sir...
Now I'm completely learned...

Sir your explanation is really Awesome but your hand writing are total Opposite to your explanation. Some time it'd really give hard time to understand what you write.
Thank you so much for this wonderful explanation . It helps me to prepare for my examination.
sir in previous lecture you said distribution function is also called as density fxn, what is the difference between these two.
Very Helpful for Data Science also...👍

Sir all yours video are too good and you explain it very nicely 😊 but in this topic i am confuse 😢
20:03 ...Before it was correct Sir when we are writting distribution function then we can't write in separate interval ...
Nice lecture sir!... Aapka padhane ka speed bhi sahi hai, mei jo bhi lecture dekhta hu usko 1.5 ya 1.75 speed pr hi dekhta hu...aapke lecture speed badhane ka jarurt bhi nhi padha....
Thank you so much sir to explain very easily to the topic
This video helped me a lot sir.Thank you so much
Find the variance and standard deviation of the continues random variable x .f(x)=3/4(1+x^2)
Very good explanation sir.....
Continue like these videos.....sir
Sir U are amazing bus ek prob hai handwritting ki. And everything is just perfect and amazing.... Thank u.
After two sessions my right ear got justice 😂😂
Sir you explain so good.
