isnt this like seeing the future?
is it correct?

All replies

now something crazy on the future teller 8 ball, IT WORKS
the key for this is that in a 2 choice option you add a virtual 3rd option
another identical thing between my program and the magic 8ball:
so you trow a 3 sides dice and every time it appears the virtual option you say plz ask another time
then applying the monty hall thing you have a 66% chance to be right following the 8 ball where if you didnt you would have just a 50%
seems the truth its been always out there:
from the wiki:
To use the ball, it must be held with the window initially facing down. After "asking the ball" a yesno question (and shaking the ball), the user then TURNS the ball so that the window faces up,

For me this shows a bunch of negative numbers...Wednesday, May 9, 2012 12:40 AM

For me this shows a bunch of negative numbers...
yes thats the money you lose in a hteoretically 50% chance game in which if you win you win one and if you lose you lose one as well
it should remain in zero but as you dont switch you lose 2/3 of times in a 1/2 chance game

edit:
its wrong, the logic is wrong its posible with this program the prize and the discarded door its the same Edited by antonio glez Wednesday, May 9, 2012 9:19 PM

here the program corrected i think its right now:
re:
'this is the door of 3 behind behind which it is the prize
a=math.GetRandomNumber(3)
'this is the door the host discarded the previous week, you have bad memory but you remember
'it was not discarded door number 3
re1:
b= Math.GetRandomNumber(2)
'this is so the discarded door is different than the price
If a=b Then
Goto re1
EndIf
'this is the door number you pick without being very sure which was the discraded door
'as you know for sure the 3 wasnt discarded you decide to always pick door number 3 initially
c= 3
'there are two left doors so its a 50% chance
If a<>c Then
'If you get the right door right you win one coin
bob=bob+1
Else
'if you get the wrong door you lose one coin
bob=bob1
EndIf
'remember its a 50% chance there being two door, if you win you win one if you lose you lose one
'now you can run the program and check how much you win by switching the pick
TextWindow.WriteLine("your gains are="+bob)
