Bayes' theorem problemThe probability that Katarina will correctly solve a given math problem is 1/8. The probability that Layla will solve the same problem correctly is 1/12. Given that they are both incorrect, the probability that they will give the same incorrect numerical result is 1/1001. 'And fun? If maths is fun, then getting a tooth extraction is fun.

Re: Bayes' theorem problemIs it 2098?

Re: Bayes' theorem problemThere's another clue which says that the answer is within 0 to 999 inclusive 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun.

Re: Bayes' theorem problem
Should that be same incorrect numerical result? In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #5 20130406 02:55:01
Re: Bayes' theorem problemI can't think of any other answer. Hi bobbym, Yeah, in that case we can have a zero!

Re: Bayes' theorem problemThey tell its wrong. 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: Bayes' theorem problemI try again 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: Bayes' theorem problemBut I wrote the same! 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: Bayes' theorem problemI know but it is good to check. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it.

Re: Bayes' theorem problemWhoops, a mistake in my previous attempt, I wasn't considering the probabilities for wrong answers!

Re: Bayes' theorem problemThat is correct! Thanks 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: Bayes' theorem problemYou're welcome.

Re: Bayes' theorem problemHi bobbym,
Did you mean the probability that answers are the same, given that both are correct? "Believe nothing, no matter where you read it, or who said it, no matter if I have said it, unless it agrees with your own reason and your own common sense"  Buddha? "Data! Data! Data!" he cried impatiently. "I can't make bricks without clay." #19 20130406 23:06:47

Re: Bayes' theorem problemS stands for "same answer" "Believe nothing, no matter where you read it, or who said it, no matter if I have said it, unless it agrees with your own reason and your own common sense"  Buddha?

Re: Bayes' theorem problemI have thought about treeing them for a while but I must have always left one or two out because I never got the right answer. In mathematics, you don't understand things.

Re: Bayes' theorem problemWill you please make it clear to me? 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'
