Got it,

Thanks bobbyM and gAr

So after all this isn't related to Bayes'?

Why do you say that?

Because I don't see where you use it

Hi Agnishom,

It is related to Bayes', we just didn't write a formula for that!

There is a formula that covers what he did, it is called the extended form of Bayes theorem.

I tried to match that too.

p(a|b) = (p(b|a)*p(a))/((p(b|a)*p(a))+(p(b|not a)*p(not a))

What you wrote is the extended form:

That has the form of his answer. That is what I was working on, trying to fill that in but I must have missed something.

His use of the tree is better, it lends itself to computation better.

Surely thats better.

But how do you use that formula?

Hi;

Look at his answer:

then look at the formula:

try replacing corresponding parts.

I did not see gAr's answer until I posted. He got the solution so he is the guy to ask.

I have the result, but I do not yet know how to get it.

Now in that part, what does A and B stand for?

Hi Agnishom;

You are forgetting that I did not get the answer so I must not have filled that formula in correctly.

I have the result, but I do not yet know how to get it.

Okay, I am contended with the tree anyway. Next time I will think of one

Yes, yes, it seems more clear but how does it fit into the formula?

I mean how do you relate the calculation with it?

Hi,

You can plug in the values now..

Hi;

I found a couple of pages that agree with his approach and also calculate the number for you.

I have the result, but I do not yet know how to get it.

Hi;

Yes, websites. Have not gone over them completely so I do not know how good their computations are.

I have the result, but I do not yet know how to get it.

May I have the link?
