Am i missing something here ?.. Thank you in advance
@jbstatistics2 жыл бұрын
Those events are based on the roll of a single die. (Thus leading to the given sample space of S = {1,2,3,4,5,6}.) The fact that we often assume repeated die rolls are independent is not relevant here. On a single roll, the probability of getting an odd number on the top face (event E) is 3/6. The probability of getting a 4, 5, or 6 on the top face (event F) is 3/6. The probability the number is both odd and a 4, 5, or 6 (event E n F, which is just the number 5) is 1/6. E and F are not independent.

It is semi clear to me now , but i still can not understand how event E occuring will effect the probability of of event F as we are rolling the die independently each one time ? .

@@mohfa1806 " i cant understand how they are dependent since each roll of a die is seperate !." I don't know what to tell you here, as in my first response I addressed this as well as I can. It does not matter, at all, if the rolls of a die are considered independent. We are talking about a single roll. The die is rolled. We look at the number on the top face. It is one of the numbers 1, 2, 3, 4, 5, or 6. What's P(E)? 3/6. How about P(E|F)? Well, if the number is a 4, 5, or 6, there is a 1/3 chance it's odd, so P(E|F) = 1/3. P(E) does not equal P(E|F), so the events are not independent. If we assume that repeated die rolls are independent, that does not mean that all events with associated with rolling a die are independent. Is getting an even number independent of getting an odd? No, of course not, since if we roll an even number it cannot have been odd. Is getting an even number on the first roll independent of getting an odd number on the 40th roll? Sure, but that's not what we're talking about in this video. I address conditional probability and independence in detail in other videos. This video is about the basics of unions, intersections, and complements.

@@jbstatisticsthank you prof. For your responses and being patient with me , i really appreciate it. And sorry for my late response to you since i was little ill in the past two days. There is still something that confuses me : When we say P(E I F) , then according to my little knowledge it means : "the probability of event E such that event F occured" . My question is : when event "F occured" , then one number occured , either 4 or 5 or 6 , as they can not occur all together in one roll at the same time. This leads me to confusion , as according to my logic P(E I F) can be equal to either 0/6 if event F was 4 or 6 , OR equal to 1/6 if event F was 5 , and since we can have two answers then this proves that events E and F are dependent . Is my logic correct ? . Thank you again for your patience

This video was extremely helpful! However, I have a question. At 13:48, why is it a union of the compliments and not the intersection? The reason I say this is because, the probability of not having diabetes would be the green region plus the probability of someone only having hypertension. While the probability of not having hypertension includes the green region plus the probability of only having diabetes. So wouldn't the probability of not having diabetes and hypertension, be the intersection of not having both? Sorry for the long winded question, and thanks in advance!

Only the probabilities of the sample points need to add to 1. Probabilities of events can add to any nonnegative value (under the restriction that each individual probability can't be greater than 1). It is very common for two events to have probabilities that add to something greater than 1.

why is P(E∩F) same as P(F∩G)? EF has 6 sample points and one common point which gives 1/6, but FG only has 5 sample points and one common point so why is that equal 1/6

@jbstatistics6 жыл бұрын
There are 6 sample points in the entire sample space. E and F share a single sample point. F and G share a single sample point. Since the sample points are equally likely, this implies that P(E n F) = 1/6 and P(F n G) = 1/6. (If one of those 6 equally likely sample points is randomly picked, there is a 1/6 chance it is a 5, and a 1/6 chance it is a 6.) E U F = {1,3,4,5,6} and F U G = {2,4,5,6}, but that's irrelevant as far as P(E n F) and P(F n G) are concerned.

Thanks a lot, Z = "Remaining un known event of the sample space" {D,H,Z} are events of the sample space S At first, this is what I did P(S) = P(H) + P(D) + P(Z) =1, P(Z) = 0.6 (you got a 0.67) but i later on realised that this only applies if the events (Z,H,D) are mutually exclusive. P(S)= P(H u D u Z) P(S)= P(H)+P(D)+ P(Z)- P(H n D) - P(H n Z) -P(D n Z) - P(H n D n Z) we donot have all the probability values of the intersection terms, so you decided to use the "complement" in order to find P(Z) : P(D n H' ) = P(D) - P(D n H) = 0.03 P(H n D') = P(H) - P(H n D) = 0.23 P(Z) = P(S) - P(D n H) - P(D n H' ) - P(H n D') P(Z) = 0.67 and not 0.6 as I thought. Illustrating it on a vein diagram is priceless, great work sir.

I'll disagree with you strongly here. There may be some spots in stats where historical language choices are in retrospect not the greatest, but here? Unions, intersections, complements? The usage of all these terms is very consistent with their use in common English. The symbol for union even looks like a U. The symbol for 'the other one' is just that flipped. If you think this terminology is terrible, you must have an alternative in mind. What do you suggest?

@@jbstatistics no, not that part of it. When people start explaining it saying unions can be A or B or Both and intersections are A and B (isn't that both as well?). Just as an example, I know we can't have 2 types of blood, but for a not mutually exclusive event why would I use intersection instead of union? Simply because I know the two types of blood thing? So doesn't that add common sense or even knowledge into the equation (atleast when interpreting someone else's data)? Thats where the wording was confusing to me as. I came here and you didn't keep saying the both with union so I took it out of my thoughts and kept it with just "or". Maybe I'm just missing something lol. Thanks for the fast response too, isn't this video 7 years old?
@jbstatistics Жыл бұрын
@@user-hp1bi7se4x In the English language, "or" can be the inclusive or (either or both) or the exclusive or (either but not both). I state very explicitly in this video that when we're using the term "or" in probability we mean or in the inclusive sense. "When we use the term A or B in probability, we are referring to their union, and using the word "or" in the inclusive sense; A or B means A or B or both." I realize this can be a point of confusion, so I get miles ahead of it and address it explicitly and as clearly as I am capable of or ever will be capable of. If I keep going on about it every time I encounter the word "or", it would be a mess. Sure, there are times when we might need to use "or" in the exclusive sense, and then we're clear about it "A or B but not both." I really don't understand what your point is about the blood types, but no, there is no ambiguity or potential discussion about whether "mutually exclusive" should involve the union vs the intersection. Two events are mutually exclusive if they share no sample points. If they share no sample points, the intersection is the empty set (there's nothing in there), leading to a probability of that intersection of 0. If two events are mutually exclusive, the knowledge that one occurs tells you that the other one did not occur. "Mutually exclusive" has pretty much the exact same meaning in ordinary English and in probability. These things cannot happen together; they are mutually exclusive. The video's 7 years old, but I'm often logged in and get notifications. I address some of them, and don't check to see when I made that particular video. Sure, it was 7 years ago that I made this, but we'll be using this same terminology in 50 years, and these concepts will still be the same.
