3but i want explanation for the theory part.
i cant understand by substituting the formula.
waiting for a serious help .............
1Its very simple!
See, we r given dat d coin is from B1
The probability of selecting B1 is 1/3
Probability that gold coin is frm b1 is 1, that it's frm b2 is 0 and it's from b3 is 1/2.
Now we can directly apply Baye's theorem:
P= (1/3*1)/1/3*1 + 1/3*1/2 + 1/3*0
=2/3
Hope u got it!!!
~~~CHEERS~~~
62sankara.. this comes from venn diagram
P(A/B) is the area fo A∩B divided by area of B!
I hope this hint helps enuf..
try to draw a venn diagram
11Sankara, you will perfect Bayes' Theorem only with more and more problems. Once you get used to it, you'll begin to enjoy it. [1]
This is my favourite topic in probability. Bhaiyyah, if you can, please post a few problems in it?
62okie.. dude i will post a couple on the "backlog" question of the days ;)
3nishant sir ur helpd a lot in understanding Bayes theorem and tx others for repling
