Thanks to all of you who support me on Patreon. You da real mvps! $1 per month helps!! :) / patrickjmt !! Thanks to all of you who support me on Patreon. You da real mvps! $1 per month helps!! :) / patrickjmt !! Thanks to my supporters on Patreon! / patrickjmt
In this video I show how to derive the Poisson Distribution.

[@shitpostheavy]

You've helped me get a Math for Education degree and now I'm a Math teacher and tutor for about 2 years now.
THANK YOU FOR EVERYTHING. Happy new year Patrick!

[@salina_y]

😊Hope you’re doing well!

[@patrickjmt]

Happy New Year Everyone! Have fun, stay warm and most importantly: be safe!

[@ishaan1]

patrickJMT happy new year 😄

[@RobertRaleySummers]

Happy New Year!

[@ThirdEdit]

Happy new year!!

[@patrickjmt]

heeeeeeeeeeeeeeeeeeeeeeyyyyyyyyyyyyyyyyyyyyyyyy! mr summers!!! how are you?!
i'm on lichess now: patrickjmt, add me if you are on there

[@patrickjmt]

happy new year to you too :)

[@amirmahmoodi4820]

You just solved half of my problems. Thank you kind sir, your explanation was crystal clear. The idea to divide continuous time into some intervals and then miniaturize those intervals so the time is continuous again was neat.

[@duckymomo7935]

I kid you not, I actually prayed for this
God is real!

[@nancyiche5100]

I love your method Patrick, 'cause you deal with more derivations. This is something that rarely happens in class.

[@dhanyalakshmi4023]

You are AMAZING! you are a huge inspiration for many of us.... lots of love from India!

[@superbros1690]

How do you stay focused in math, im going to take calculus this semester and i need to know your secrets to success in math, if possible can you make a video or reply thanks.

[@Nightskyfrog]

Thanks for the video! Just one note, on 5:30 I thought that's the formula for binomial distribution, not bernoulli distribution, since it's not just a single trial?

[@tubesteaknyouri]

You are correct. A Binomial is the sum of iid Bernoulli random variables.

[@kapishjalan7393]

Yes, I was thinking of the same thing.

[@usamabhatti3559]

Grate it is very helpful understanding to poisson distribution

[@mengzhu8385]

helped me a lot when I'm reading algorithms on hash tables

[@nimasadeghi7810]

Tnx bro it's really helpful.

[@md.nazmulhaque7207]

Hey! PatrickJMT your channel is best Math channel to me. So I want to download all your videos. So please can you make new playlists with every 350 videos???!!!???

[@benwinstanleymusic]

This is really helpful, thanks

[@salmanahmad1]

I just watched his 8 year old video and now this. And his voice has changed a lot.

[@laurynchan9877]

Hi! So what is lambda defined as?

[@cesalonsomulder1990]

Thanks a lot for this derivation !!

[@kapishjalan7393]

Thank you for the explanation!!

[@YouUndeground]

Thank you for this great explanation!

[@patrickjmt]

You're very welcome!

[@jakobb.4214]

great video !

[@naveednaiemi3979]

Happy new year; ya it will be great to have more probability videos

[@aenimosity7]

Great video, thank you!!

[@bosepukur]

Thanks for the video Patrick :)

[@user-ko6oe4sp6y]

Hello, Patrick! Which book did you use when preparing this video?

[@hostilebuffalo]

Do you have official merch? If not I genuinely hope you consider it

[@miodraglovric5093]

Patrick, in 4:23 you are confusing Bernoulli with the Binomial distribution

[@jamesfullwood7788]

Was going to comment the same thing.

[@aravindssingapore4327]

I see you are married to Mathematics. You are a very good professor, Patrick

[@aravindssingapore4327]

The Poisson Distribution is a lovely fish

[@patrickjmt]

i am married to a professor of mathematics, this is true :)
thanks for the kind words though :)

[@EricsShitposting]

nice explanation

[@randomsnaps5912]

In the poisson prob. distrbn. how can we derive out the mean value, variance , and
moment generating function

[@vasuyadav2931]

Everything else id clear but I don't understand the reason behind taking n ->infinity. Can somebody explain?

[@venom5562]

helped thanks !!!!!!!!!!!!!

[@InAweofhisglory]

isn't that the binomial distribution, not bernoulli?

[@user-bf3bx6su3g]

Thanks

[@dwivedys]

Patrick request you to please do a video on Gamma Distribution- regards

[@borisbryant.007]

drop the link of the book below

[@ahmedhadwan9273]

Sir, I do not know how to thank you.

[@user-ux1nt9dz3o]

i love you

[@rakshithgowda1606]

Is there a way I can ask you questions?

[@user-yz2sl5bv8p]

Can you help me in Differentiation and Integration Power series

[@patrickjmt]

i'm busy getting tipsy at the moment and have to make a delicious dinner so probably not. it is new years, not homework time.

[@davidmoraes1488]

Soo, what the heck is lambda

[@leakingboat]

X

[@lukezeng8734]

that's not Bernoulli?!??!

[@borisbryant.007]

5:41 binomial distribution formula

[@EdwardGainesII]

Ib math hl problems

[@Hobopower84]

I'm stuck on the step where you simplified n!/(n-x)! to n*(n-1)*...*(n-x+1). I know I'm missing something easy here. Anyone willing to explain this further?

[@burakguzel3209]

Sterling Sharpe hey, he just uses the definition of what is called a permutation, i.e. P(n,x) = n(n-1) .... (n-x+1) or which can also be written as (n)!/(n-x)!

[@Sporkabyte]

n! Is the product of all of the integers less than or equal to n, and (x-n)! Is the product of all the integers less than or equal to (x-n), so dividing (x-n)! From n! Cancels all the integers in n! That are in (n-x)! or anything less than (n-x+1). So you’re left with the product of integers from n to (n-x+1).

[@ollymrichards4093]

please do pythagorous theorem and trigs

[@sjchsbc]

Anelka King There are also many other great videos on them.

[@duckymomo7935]

Pythagorean has 300 different proofs alone

[@patrickjmt]

i have

[@rdnetala]

Are you good? your view counts seem to have gone down a lot.

[@and_still.]

Plz make video of integration of (√cotx +√tanx)dx.
