THE BEST THANK YOU: www.examsoluti...
delicious intro music
Just want to thank you for the unbelievably good job. This is a lot of effort from you. I really appreciate it. I wish I were a millionaire or something so that i could reward you for your great work and your contribution to high quality education. I watches most of your videos and I am really impressed. Thank you very much
2:36 seconds it took me, to learn what I've been trying for 2 weeks now. Thank you!
Thanks!
You made life easier for me to understand clearly the probability of at least one package being delivered on time, when you divide the order between the two vendors in hopes that at least one of them will deliver on time. P (x)=.9; P (y)=.9
P(x')=.1;P(y')
It is
P(x)*P(y|x)+P(x)*P(y'|x)+P(x')*P(y|x')=.9*.9+.9*.1+.1*.9=.99
or
1-P(x')*P(y'|x')=1-.01=.99
Thanks again. The solution in the book simply says the answer is .9+.1*.9 and confuses.
You are the best. Excellent!
Thanks a lot. Good luck in your exams.
EXAM SOLUTION is the best all the time
I hope exam solutions lasts till my children are students😎😎. This channel is my savior
Thank you
really u r very good tutor, i make MSC in project management and im stragelling in probability and statistic specially when it comes to Distribution and bayes passion...
The best conditional probability explained. I will plant a tree now.
Yes there is a difference. Check out my tutorials on conditional probability.
@itsmycornetto Welcome to the UK.
Hi, could you tell when we multiple and when we add probabilities ?
In the other video u said the only independent events' probabilities can be multiplied.
Thanks a lot.
In the example of the formula using A's and B's, wouldn't this make "event" B occur before "event" A in the probability tree?
Does it matter, do we have to know, if the events in the tree are statistically dependent or independent, when using conditional probability, to find some kind of probability?
Is it true, using the tree, WHENEVER you add the probability of events to find some kind of probability, the events being added are always mutually exclusive?
Can you please clarify my confusion?
Greate explanation ! Best one ive found !
I have used the tree diagram & the conditional logic to find the probability of the last of the activities in sequence will finish on time. If any of the activities are late, the entire project is late. P(A)=.9,P(B)=.9,P(C)=.9. are probabilities each activity will finish on time
P(A')=.1,P(B')=.1,P(C')=.1
are probabilities that each each activity will finish late
The top branch of the tree gives the answer.
P(A)*P(B|A)*P(C Given A Given B)=.9*.9*.9=.729
im so worried my exam is on the coming friday, and the only topic that is really confusing in s1 is probability, cuz there are questions like language barriers and those given formulas are confusing.
hope it went well lol
Thankyou!
Why do you divide it by b
what if it was depenent? not independent?
Cool
real GOAT
I was 5 when this was uploaded...
awsome
@dvssk8er3 Hope it goes well but please leave my cheeks out of it thanks.
December 2018 anyone????
Example better !
Isn't that formula given to you? Kind regards
It's in the formula book
uk is the best haha
you made this sound un necessarily difficult like some algebra equation, try and actually use real life situations like they would in exams
