deadie:No the question says what is the fewest number of marble you could remove from the boxes and look at in order to definitely determine the content of all the three boxes not the number of times. Simple English. |

Ichiato: No the question says what is the fewest number of marble you You are probably the one who does not understand simple English. Must I use exactly the same words that he used? I read the post once and understood the content and did not need to memorize the exact words used, Mr/Ms. complex English. Mind your language. In order words, I need to look at 3 tiles/marbles to identify the boxes if you will. |

deadie:If the number of marbles you have to pick to rightly determine the content of the boxes is the same has the number of times you're allowed to pick then I rest my case. |

MoyoGENERAL: There are three boxes which each contain two marbles: one has two white, one has two black and one has one white and one black marble. Each of the boxes also is labelled as to its content, but each label is incorrect. What is the fewest number of marble you could remove from the boxes and look at in order to definitely determine the content of all the three boxes? 4 is the answer I guess. From the labels, though incorrect you deduce we have 3 white and 3 black balls. And when you have picked from the 1st 2 boxes, you get a 100% idea whats in the last box. |
Re: Believe Me, This Is Going To Make You Sweat!.the Best Of Puzzles. by Nobody: 8:49pm On Jul 12, 2014 |
let me try again initially misread the question. the answer is surely surely one ball oh.had to draw it out.lets say the boxes are incorrectly labeled xBB,yWW,zBW.knowing that zBW is wrongly labeled,that means zBW is actually WW or BB.xBB cant be BB,yWW cant be WW. so if you pick W in the xBB box,that means it contains WB cus,yWW cant be WW .so xBB is acually WB,then yWW is BB and zBW is WW.emember it is the best possible odds.the boxes can be picked in any order,the probability remains 1. |

Six(6) is my answer. The only way you can properly label the boxes with respect to its content is by taking out all the content and simply putting them back. Then you label them properly. ie, take out the 2 in box 1, 2 and 3. 2+2+2= 6. *bows* 1 Like |

hiroz: you need just 1,if you pick the black ball,you know what the others are.there is just 1 black ball and 5whites.the question said the fewest number of balls.here is my example,if only 1 nairalander has blonde hair,and we are 1million,if seun has to pick that single blonde the range of probability is from 1 to 1million while eliminating each wrong choice and fewest chance here is 1,cus improbable as it may be,seun could pick the blonde nairalander at 1st guess..You did even understand the puzzle at all, there are (2whites), (2black), (1white & 1black) assume the bracket to be the boxes, so we have total 5backs and 5whites. Go back and read it again. And If you pick only one then how will you decide which box has WW BB or BW. Humbly waiting for your answer. 1 Like |

Two marbles to ensure all boxes contain a mixture. Bb | ww | bw Pick one white and one black from the |bb| and |ww| boxes to give you: Bw| bw | bw So irrespective of label, you know each box contains a bw combination and have definitely determined the contents. |

You must remove two marble from at least one of the boxes. Explanation: 2/3 of the boxes contain at least 1 white or 1 black. Assuming you pick a black from box A, a white from box B and a black from box C. If in your second draw,you pick a white from box A. Then box B contains all white and box C contains all black. If however your second pick from box A turns out to be black, then you must see the colour in either B or C to know the colour in the remaining box. 1 Like |

The answer is ONE(1). Remember the boxes re all labelled incorrectly. Assuming we ve boxes XYZ with content (x)WW (y)BB (z)BW respectively but INCORRECTLY labeled (x)BW (y)WW (z)BB. If we pick one ball from box X which will definitely be a white ball(W), it will invariably mean the other ball is white bc the label says BW which is KNOWN TO BE INCORRECT in d first place so box (X) ascertained to be WW. Since we now know tht box X is WW then it means tht box Y can only b BW or BB nd box Z can only be BW or BB. Y= BB or BW Z= BB or BW Remember box(Z) IS INCORRECTLY marked BB, therefore it cannot be BB but BW nd since we now tht box Z is BW then it invariably means box Y is BB. Am I on track? |

white= w black = b we have the following colors in each box ww bb wb there is a probability of 2/3 of the same colors in the three box. the possible number of times to correct wrong label is 2. 1. WW--label-WB 2. BB--label-WW 3. WB--label-BB Answer. first move. move B in 1 to W in 2 second move. move W in 2 to B in 3. |

MoyoGENERAL: There are three boxes which each contain two marbles: one has two white, one has two black and one has one white and one black marble. Each of the boxes also is labelled as to its content, but each label is incorrect. What is the fewest number of marble you could remove from the boxes and look at in order to definitely determine the content of all the three boxes? 1 ball only. Let the incorrectly labeled boxes be WW, BB, WB. Since the boxes are labeled incorrectly, then WB contains 2W or 2B, WW and BB can contain 1W1B or two balls of the same colour. Consequently, we pick one ball from WB only. If we pick a black ball from WB, then WB contains 2B, WW contains 1W1B and BB contains 2W. However, if we pick a white ball from WB, then WB contains 2W, WW contains 2B and BB contains 1W1B. |
