Four month trial, you only get 1 shot .

15 jars in a row, you cannot see into the jars , in each jar there are 6 marbles 2 of the marbles are painted red the other 4 marbles are black .
Ok  you place your hand into the jar mix around and must take out any 2 marbles at once with out looking . Q. what are the odds on going 15 in a row with out ever taking a red marble.
I know the answer . This system makes £40 to £80 a day every day . if you get it spot on I could divulge the system . No fee all free .

I'm having a dumb moment, but how can there be a decimal place when there's an intergral number of combinations?

Report BJT August 1, 2011 12:49 PM BST
Well I am certainly no expert and your question confuses me.  I simply know how to work it out, so I am assuming the conversion to the 1/ is the problem?

I was being particularly dumb.

I was thinking there was only one "winning" combination of events, which would mean it should be 1 in xxxxxx.00

the numerator and denominator have to be integers lori, i.e. 32768 in 30517578125

Ahh ok, but in reality only the combination of all possible results should be one, leaving decimal chances all over the shop.....

Cheers DStyle, I got there in the end. Feeling incredibly silly now.

Good thing I don't rely on numbers for... wait, crap.

So the answer is right, just the formality of the writing of it is wrong yeah?
Report Lori August 1, 2011 12:55 PM BST
It's just right, I was being dumb.

If the question was selecting both red balls from each jar, then it would be 1 in xxxxxxx.00 because of all the possible combinations there would only be one "winner"

As DStyle points out, in the real question then there are xxxxx ways in xxxxxxxxxxxxx to actually "win" which can easily result in a decimal.

For each dip, there are 30 combinations (6 first marbles * 5 second marbles); of these combinations 12 are all red marbles and 18 have at least one black marbles.  So the probbaility of not getting a black in a single dip is 12/30 (=2/5, same as BJT).  So probability of not getting a black in 15 dips is

(2/5)^15 = 0.000001073741824 or 1 in 931322.57 approx (as BJT).

@Lori - what's the issue with the dp?  The probability is 32768 in 30517578125 (2^5 in 5^5) if you want it in integers, it's only expressing it as '1 in ...' gives decimals.

There are 2 answers possible due to uncertain condition in the question.

Question condition 1 , 15 lots of 2 red marbles in a row
= 1 in 91552734374.9999  chance.

Question condition 2 , 15 red marbles in a row
=1 in 703125 chance.

Considering the vagueness of the free trial offer in the OP, is this perhaps one of those comps. you might be better off not winning ?

the odds are 0/1 or 1.00 or 100%, assuming of course you are actually trying not to pick the ones that have been painted...

Well it isn't really a puzzle is it, just a probability equation.  System works good though, all the time I have spent in this forum over the last couple of days has easily saved me 40-80, and then some...   :)
Report bf_fananatic August 2, 2011 11:58 AM BST
I know bjt it was a probability question, my answer was correct but for getting sequences of red not black, whoops. If only the probability equations needed to tissue price a race was as easy to formalize!

But the interpretations of factors single and grouped and there singular and global effects on prediction accuracy are very complex, add to that chaos theory, variable external conditions, track variability and missing factors and many x factors and you certainly do have a puzzle on your hands that calls for new probability concepts for working on related data fields.

As usual as in the past when commercial software could never give me the power I needed and I created my own I also having studied statistical analysis and found little on prediction modeling that was useful I had to ad hock, trial , think tank and discover new "missing" important devices missing in the field of probability calculation, I can never reveal the nature of the said "devices" but believe me there is so much in the known and unknown world or universe that we cannot hope to decipher it without one day resorting to AI , computers are opening new doors everyday and most new discovering involve the application of computers, super computers sometimes, these are indeed exciting times!

does everything, it collects the data in and not only does it do the normal routine stuff that prediction software runs but it finds the formula for you , tests it, refines it and so on in real time

Hi bf_fanatic.

'Contrarian' is not a made-up word. See http://en.wikipedia.org/wiki/Contrarian

My issue was with your spelling, not your grammar. Sorry, but after reading your endless posts full of poorly written drivel, I had to say something.

Here's another site that may help you:

Poor question really, answered correctly virtually immediately.

I remember starting a thread asking what the probability of a sequence of at least 5 heads in 20 tosses of a fair coin is. There's a seemingly simple problem that very few people can solve [;)]
