### Re: "Monty Hall" Three Doors Problem

But for practical purposes, given well-manufacture dice, the variations are tiny, and the theoretical probability models work well. Other games, like betting on horses, can't be modeled as completely and effectively. Another area that may be of interest is that of phenomena where we know perfectly ...

### Re: "Monty Hall" Three Doors Problem

I think it can be shown that any device that gives Joe a chance to switch improves his odds of winning, if Monty has opened some doors. And switching with certainty is the best strategy. Yes. Assume there are n doors in total, and Monty opens m of them, where m < (n - 1). If the player does not swi...

### Re: "Monty Hall" Three Doors Problem

Now, if Joe flips a coin to decide whether to switch in the first place, the chance to win reverts to 1/3 ( or does it? -- maybe greater than 1/3? Another puzzle). The overall probability of winning becomes 1/2. Suppose that heads means switch. Half of the time he does not switch, and has a probabi...

### Re: "Monty Hall" Three Doors Problem

Sorry are you refuting that switching is always an advantage? No, I am saying that switching is always the right thing to do, because it increases the probability that you will win from 1/3 to 2/3. There are plays of the game on which you will lose by switching: those plays when the prize is behind...

### Re: "Monty Hall" Three Doors Problem

It's 2/3. The point is that the prize does not have any chance of moving after Monty opens a door (say one of B and C, the player having chosen A), behind which the prize is not to be found. So it is not 1/2 because it is not the case that after that opening, the prize is randomly allocated between ...

### Re: Poetry here.

But if passion can be a product of brain cells then why can't God? Both can only be felt and not seen....right? Well, belief in God, a sense of God, and so on could be, indeed are, a product of brain cells (plus the surrounding society of other collections of brain cells and what they have construc...

### Re: Poetry here.

Can you understand the theist any better when you apply the same sentiment to them? When aesthetics come to life so intensely that you feel it's breath on your neck...how is it possible not to believe? Not that I have had that experience with God breathing down my neck...he has not yet made his pre...

Thank you for your kind comments, AS. The tone I had not noticed, but now I see what you mean. Be assured that the gods have given me no talent for creating visual art, or music, or for driving horseless carriages.

### Re: Histories of Philosophy

There are 8 volume of the book A History of Philosophy by Frederick Copleston which will be good source. There are 11 This discrepancy is easily explained. There were originally eight, then three more were added (one on French philosophy, one on Russian philosophy, and a slim one on logical positiv...

### Re: philosophy of mathematics

As to a philosophy of math: Here is a proposal that is philosophical and has to do with math: The operations of mathematical symbols only reflect a valid operation in their basic relations. Once interpretation takes place, math has been removed from actual presentation (identity) of the phenomenon ...

### Re: Logic by the good Reverend Dodgson.

A quick glance at the books suggests that they essentially do syllogisms with Venn diagrams, and use an ingenious square form of diagram, rather than the more usual overlapping circles, in order to keep the diagrams clear when there are several properties that objects may or may not have (with three...

But no AS, it is encouraged, with him to argue. That way can one more learn. And if you more fun with him have would like to, can you this piece enjoy:
