Assuming all is based on statistics, what are the chances that a bill is a radar (ie 1 out of x are radar bills)... I'm not sure how to come up with an equation that would solve that. I'm curious because after searching hundreds of dollars, I finally found one!!!

Each brick has its own four beginning numbers. One of the bills in that brick of 1000 will have the opposite ending four.   03-31-2006, 05:14 PM   #3 (permalink) xeno108 Senior Member     Join Date: Oct 2005 Posts: 433 in that light, would it not be one in 10,000? because it would take 10,000 bills to change the first four numbers? 12340000 - 12349999 (radar is 12344321)   03-31-2006, 05:48 PM   #4 (permalink) NickTheHobo Junior Member   Join Date: Mar 2006 Location: Mount Laurel, NJ Posts: 10 snap. i guess ur right. the theory works though. __________________ Chuck norris can divide by zero.   04-01-2006, 01:28 AM   #5 (permalink) Jimm1514 Junior Member     Join Date: Mar 2006 Posts: 20 Another Member turned me on to this website.

It says that the odds of finding a radar are one in one hundred (0.010%) but I'm pretty sure thats wrong. __________________ Chuck norris can divide by zero.   04-07-2006, 02:34 PM   #10 (permalink) genetic Junior Member   Join Date: Apr 2005 Posts: 25 I agree that one in 10,000 is correct. For each of the first four digits, there is a 1/10 chance its mirror digit matches. Thus (1/10)^4 = 1/10,000.   04-07-2006, 07:27 PM   #11 (permalink) satootoko Retired   Join Date: Mar 2004 Posts: 5,822 Quote: Originally Posted by NickTheHobo It says that the odds of finding a radar are one in one hundred (0.010%) but I'm pretty sure thats wrong. Actually, if it says .01% that's correct. At least 1/100 of 1 percent was 1/10,000 of unity when I took 4th grade math, before "New Math" came along. . __________________ Roy   Bookmarks Digg del.icio.us StumbleUpon Google Would you like to support CoinTalk?
