yeah he is CRYSTAL CLEAR in all of his lectures . straight to the point . most important point is that he takes minimal time and teaches maximum of the topic . Very few can maintain this balance between precise explanation , wonderful time management , and the way he presents the topic, keeps the concentration going on till the end of the lecture . thank you very much jbstatistics
Thank you SO much. I was nearly in tears trying to understand the jibberish our lecturer was throwing at us. You give clear explanations of WHAT is happening, HOW and WHY, which is what students need and teachers just don't get it :(. Your videos are giving me hope to pass Business Statistics ! Thanks again.
omg, you are the best. I hope you do well in life. I am in this class where my teacher has absolutely 0 idea of how to teach. all she does is just read the slides and expect us to understand all of this. it is so stupid and frustrating. I got a quiz worth 5 percent of my grade and an assignment worth 8 percent of my grade to do this week. you are a lifesaver.
Sir, you're truly a legend!! If I didn't find you on youtube I might fail the class!! I have a test tomorrow watching all your tutorials. Already watched the whole playlist of basics of probability, now I'm on this one. Thanks again
Thank you very much for this and every video of yours. I've been through so many videos of statistics before coming to your videos. And you are simply the best. Your clarity and precision are outstanding. Thanks again :)

No, it wouldn't work as is. If you want to write P(X=3) = 1-p and P(X=4) = p in one function, then you'd have to tweak the Bernoulli pmf to P(X=x) = p^(x-3)(1-p)^(4-x) for x = 3, 4.
Khan Academy is good for most things. Their strength is the sheer amount of topics they cover. But in general, I find more specific channels like jbstatistics, are better for learning specific topics. Well done, jbstatstics, you did a great job on your channel.
Question.. let's say I pull an American adult once a month. And number of American adult lawyers increases over time (p changes over time). Is this still Bernoulli distribution?
For the Bernoulli, n = 1, so each time you draw an American the # of lawyers you get (0 or 1) is Bernoulli. The following month, n=1 again, and you once again have a Bernoulli r.v., this time with a different p. Same idea in the following months. Each and every time it's Bernoulli, just Bernoulli with differing p. If you're asking whether the sum of those Bernoulli random variables would have a binomial distribution, then no, no it wouldn't (since p changes from trial to trial).
Is the Bernoulli distribution the same as the "normal" distribution? It was asked in the sample exam but I wasn't able to find anything indicating or denying it :/ Update: Normal distribution is in the topic of Continuous Random Variables, and not in Discrete Random Variables, so the 2 cannot be the same under any circumstances.
They are very, very different distributions. Pretty much the only thing they share in common is that they can both be labelled as probability distributions.
The probability of getting two lawyers in a sample of one person is generally accepted as 0. The example is not wrong. X represents the number of lawyers in s sample of size 1. In other words, is the person a lawyer or not? A Bernoulli random variable results from a single trial of a yes/no 1/0 scenario.
Hi, could you kindly clear my doubt? What if we pick more than 1 sample in a trial? Would that still follow the Bernoulli Distribution? Or are we allowed to only pick 1 sample per trial?
A Bernoulli random variable is one that takes on the possible values 0 and 1. If you have a situation where your random variable takes on values that are different from those, you don't have a Bernoulli random variable.
Thank you very much for answering! However I do have this doubt ... even if we pick 2 samples i.e. if we toss 2 coins, the possible values the coins can take on are 0 or 1. Is this a Bernoulli Distribution or some other? Could you kindly help me with this please?
You need to be a little more precise with the problem. You're tossing 2 coins. Coins aren't random variables on their own -- they are coins. What are you counting? What is your random variable? What values can that random variable take on?
Okay sure! Suppose I want to count the number of heads that comes up when I toss 5 coins in a single trial. So the random variable is - number of heads, the possible values that it can take on are H or T. So what would be the distribution of the number of heads in this case? Would it be Bernoulli still? Thank you in advance for your help!
If you toss 5 coins and count up the number of heads, then the possible values of that random variable are 0, 1, 2, 3, 4, 5. The possible values of the random variable are not restricted to 0 and 1, so it's not a Bernoulli random variable. If the coin tosses are independent with a constant probability of success, then the number of heads follows a binomial distribution. (A binomial distribution with n = 1 is a Bernoulli distribution.)

thanks bro, u better then ma teacher. and u gots da good voice
far much better than ma lecture's notes
Man I love you..Missed those lec in the Uni and I have finals from another week..Now I'm learning from you..Thank you sooooo much :D
sorry a little bit too abstract for me. Very unclear what the difference between X and x actually is. Also no idea how to find p.
It's basic algebra bro X and x are the same place holder. Eg- X = x could be X = 4.
hey guys, quick questions, can we assume x = 3 or 4 instead of 1 or 0? Would that function still hold?
No, it wouldn't work as is. If you want to write P(X=3) = 1-p and P(X=4) = p in one function, then you'd have to tweak the Bernoulli pmf to P(X=x) = p^(x-3)(1-p)^(4-x) for x = 3, 4.
Youve just saved my life
So little x can only be 0 or 1?
Yes
Wow bro what an explanation Thankssss😇😇😇

extremely helpful video. Superb explanation
Do all descrete probablity distributions depend on bernoulli trail? Or there are descrete distributions that depend on other trails?
YOU ARE AMAZING SIR maybe god bless you!
Kindly why the mean equals to "p"? Should it be "[ (p) + (1-p) ] / 2" = 0.5 ?
Thanks for the great videos you have them here
Perfect explanation, thank you so much!!!
Thanks, this was very clear.

If you're asking whether the sum of those Bernoulli random variables would have a binomial distribution, then no, no it wouldn't (since p changes from trial to trial).
Sorry although you said there is not too much difficulty, but I still don't understand why variance= p(1-p)
this is incredibly clear. Thank you!!
Hold on, I dont understand why the variance is p(1-p), why is it the p of success times the p of failure?
I derive the mean and variance of the Bernoulli here: ua-cam.com/video/bC6WIpRgMuc/v-deo.html&ab_channel=jbstatistics
@jbstatistics holy cow what a fast response, thanks sir
Does it relate to logistic regression ?

power of 0=1
so p(x=0)=(1/200)power 0.(1-1/200)power 0=0?sdnt it be 0?
how it is 199/200?
please explain in detail sir
P(X=0) = (1/200)^0(1-1/200)^(1-0) = 199/200.
