Exercise in Probability!!!!Hi!!!I hope you can help me at the following exercise: #2 20130414 21:51:53
Re: Exercise in Probability!!!!Hi; 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. #4 20130414 21:59:59

Re: Exercise in Probability!!!!Well, I used the inclusionexclusion principle on the negative event.

Re: Exercise in Probability!!!!Ooooh that is nice one. I have a better question... Where did you get it from? 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. #12 20130414 23:26:56
Re: Exercise in Probability!!!!Get what from?

Re: Exercise in Probability!!!!Ooooh that is a good one! You are in good form today. What? I certainly did not mean the Eiffel tower. The equation, I do not know it. So I figure it is some book that I skipped over. 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: Exercise in Probability!!!!It can be found in any common textbook. AuB=A+BAnB.

Re: Exercise in Probability!!!!Which common one would you recommend? 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: Exercise in Probability!!!!Well, I do not know of any you could read, but there is an article on Wikipedia on it. Search for "inclusion exclusion principle".

Re: Exercise in Probability!!!!The Wikipedia article covers PIE but it does not explain the formula in post #8. 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. #18 20130414 23:47:09
Re: Exercise in Probability!!!!No, I derived the formula myself using the PIE.

Re: Exercise in Probability!!!!Hmmm, have you tested this formula? 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. #20 20130414 23:50:37
Re: Exercise in Probability!!!!Hm, I just found an error concerning the numbers. Let me fix the formula.

Re: Exercise in Probability!!!!Did you fix it? Now how about a verification? 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. #22 20130415 00:09:39
Re: Exercise in Probability!!!!Which kind of verification do you need?

Re: Exercise in Probability!!!!We could run a simulation. We could substitute numbers and at least see whether the formula works for a few examples. It can not prove the correctness of it but it sure can prove it false. 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. #24 20130415 00:19:25
Re: Exercise in Probability!!!!I tested for a few values and it works.

Re: Exercise in Probability!!!!M code please? 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.
