Calculating OddsHello, I would like to know the odds of getting the total of 3 RANDOM 3 digit numbers correct without ever seeing the numbers. #2 20060120 13:45:16
Re: Calculating OddsDepends how you define a 3 digit number. Is 001 a three digit number? "In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..." #3 20060120 15:02:02
Re: Calculating OddsI am a performer (Mind Reader) and I needed to know for one of my effects and I'm not very good with math. Thanks very much! #4 20060120 22:31:34
Re: Calculating OddsTechnically, the probability would change depending on which total you chose. Why did the vector cross the road? It wanted to be normal. #5 20060122 15:34:26
Re: Calculating OddsWell it doesn't matter too much, but if it's easy for you guys to give me the answer than the odds for the total of "1455" would be helpful. If it's difficult though it's not that important. Thanks! #6 20060124 02:24:47
Re: Calculating OddsThanks to the power of Excel, I can now reveal that the probability is 570058/729000000. Why did the vector cross the road? It wanted to be normal. #7 20060124 04:39:55
Re: Calculating OddsYou used excel to find the number of permutations for each sum, from 300 to 2997? How, and how long did that take? "In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..." #8 20060124 04:59:18
Re: Calculating OddsThe spreadsheet works out permutations, which is what's needed here. Why did the vector cross the road? It wanted to be normal. #9 20060124 09:02:34
Re: Calculating Odds
Yes, the general probability is different than the probability for a specific number, just like throwing 2 dice "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #10 20060823 06:59:09
Re: Calculating Oddsbut if u were a real mind reader u wud of read da mind of sum1 hu is good at maths and seen their answer, dat wud hav bin more impressive
