@rajhiranandani1007
@rajhiranandani1007 4 жыл бұрын
@ 4:05, it should be probability of A event as 2/5 (bcoz you have defined A to be the event where you get black marble) @ 6:15, in the formula in the denominator it should be P(A) Also one small thing which should be mentioned is that in Bayes theorem the events must be mutually exhaustive (that is the whole sample space is partitioned into events)

Hi Krishna, I have been following you since last year. Your videos are very informative, concise and helpful. My comment is not related to this particular video but in overall. I do have a request to you for a video answering the following question: how the cost function for logistic regression differs from the cost function used for typical linear regression. In both cases how does the calculation of parameter values depend upon finding the minimization of the cost function?

And P(B|A) is also the same scenario when A event has occurred and we r having 1 black marble out of 4 marbles. Then how we will differentiate between the two. As we have done P(A)*P(B)=2/5*1/4=1/10

@noname-gh8pf
@noname-gh8pf 3 жыл бұрын
there is no such thing as dependent events merely because something depends upon other unless it has some meaning . Even to be called for independent there should be something to be depend on. i mean you can not put the demarcation between dependent and independent. even dependent events use the independent theory (multiplication theory). for example, a man of eighty has less chance of surviving than a healthy young man. probability is dependent on his age. but the probability of his infatuation of woman is likely to be same even though chance of infatuation depends on his age(in this case). while computing this probability (infatuation) you use the independent formula to the dependent one. for the sake of linguistic purpose, yes you can. people have misunderstanding about it. independent events is mathematical but dependent is just a word in English. i have never seen any book quoting about the dependent event.

In fact, be very careful with the explanation made, is a good one but, Krish, unfortunately, used the same laters in "even B" and probability of taking a black p(B), their fore in his explanations sometimes he uses p(a) = probability of occurring the event A, (min 6: 25), the p(B)= 2/5 is for him the probability of occurring the first event, taking a black (B) = event A.
