Re: rat run probabilityAny of them 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: rat run probabilityLet's look at the first one: 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. #28 20130331 21:36:52
Re: rat run probabilityWhy 3 variables? 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: rat run probabilityBecause there are 3 rooms to exit 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.

Re: rat run probabilitySo how would I count the things basically? I am confused 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: rat run probabilityIs it possible that we can do it manually? 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: rat run probabilityNot really the problem is it is difficult to tree because the rat can go to 2 and then back to 1. Because he can can backwards the rats path could be very large.

Re: rat run probabilityAnd if we simulate we have to simulate each case for a finite amount of turns 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.' 'God exists because Mathematics is consistent, and the devil exists because we cannot prove it' 'Who are you to judge everything?' Alokananda #35 20130331 22:53:18
Re: rat run probabilityI would choose something like 100 moves. It is possible the rat might still be in the maze but very improbable. So you would have a good estimate, which is what a simulation is. 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: rat run probabilityOkay let me do it 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: rat run probabilityOne question, can the rat enter once it has left? Last edited by Agnishom (20130331 23:21:57) 'And fun? If maths is fun, then getting a tooth extraction is fun.

Re: rat run probabilityOnce the rat has left the rooms to go into the outer chamber the game is over. In mathematics, you don't understand things. You just get used to them.

Re: rat run probabilityIs my simulation okay? Last edited by Agnishom (20130331 23:37:22) 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun.

Re: rat run probabilityYour answer is close to the exact answer of 2 / 13 for a. In mathematics, you don't understand things. You just get used to them.

Re: rat run probabilityThank you 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: rat run probabilityFor c) I am getting 0.352179 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: rat run probabilityThat is very good thinking, notice that your simulation backs that idea up. In mathematics, you don't understand things. You just get used to them.

Re: rat run probabilityWhich M are you talking about? 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. #47 20130401 09:18:06

Re: rat run probabilityMathematica is superior to all when it concerns mathematical programming. I have tried them all and will not use anything else. In mathematics, you don't understand things.

Re: rat run probabilityBut, I want you to show me how to do simulations in it.

Re: rat run probabilityThere are many ways to use M's probability functions to get simulations. If you have the PDF or the Markov matrix, M can run a simulation just from that. 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.
