slapdash Posted April 22, 2006 Share Posted April 22, 2006 Re: Gizdalord from the evil Hungary I agree, Guesswest, give the guy a chance! It was wrong for him to contact Pene on MSN after she'd indicated it wasn't welcome, but I don't think there was any malice in it. I hope you stick around, Giz, and become our "Hungarian Correspondent". Quote Link to comment Share on other sites More sharing options...

davidmphill Posted April 22, 2006 Share Posted April 22, 2006 Re: Gizdalord from the evil Hungary I've a question for you to answer, well 3 actually!? A supermarket sells 2kg bags of new potatoes, in which the potatoes have been selected to be all roughlythe same size. The potatoes used to fill the bags may be assumed to be randomly chosen items from a population in which the mass, in grams, of an individual potato is normally distributed with mean 90 and standard deviation 4. (happy where we are?) (Good, right here we go) 1. Show that the probability that the total mass of 21 of these potatoes exceeds 2kg is very small 2. Find the probability that the total mass of 22 of these potatoes exceeds 2kg 3. The machine filling the bags delivers potatoes one by one until a total mass of at least 2kg is reached. Show that the bags are almost certain to contain either 22 or 23 potatoes. I'm happy with my answers to 1 & 2 but am struggling a little bit to get my head around number 3. Any advice from you would be gratefully received. Thanks in advance Dave Quote Link to comment Share on other sites More sharing options...

And 22 potatoes will weigh maximum 2068 grams... but you want probabilities?? In fractions?? About the filling mashine.... I would think that it will fill potatoes in the bags, which weigh either: 86, 87, 88, 89, 90, 91, 92, 93, or 94 grams. Assuming that ... erm... 2 of each is in a bag... that is 18... weighing 1620 grams... We need 4 or 5 more... taking them from the middle, with less deviancy... 88, 89, 90, 91, 92... ... and we have 23 potatoes weighing 2070 grams... Well... I am quite sure this is NOT what you're looking for... having troubles breaking it down to rough mathematical language... Slapdash???? But hey...
