So the answer is 175,742,424.<br /><br />I even had this on a test once. You would think I could remember how it's done.Anonymoushttps://www.blogger.com/profile/18153935609499338685noreply@blogger.comtag:blogger.com,1999:blog-15628310.post-53258582368971211352010-09-22T06:08:13.890-04:002010-09-22T06:08:13.890-04:00Is Sadeesh correct?

By doing (26^3 x 10^4) - 1 you will only remove one of the combinations that contain 0000. <br /><br />For example, you may have removed AAA 0000, but you would still have AAB 0000, AAC 0000, etc.<br /><br />Should the answer not be 26^3 x 9999 = 175,742,424?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-15628310.post-16942538411620267132010-09-21T12:57:43.521-04:002010-09-21T12:57:43.521-04:00I think sadeesh is right, 175,760,000 - 1 is the a...I think sadeesh is right, 175,760,000 - 1 is the answer I had. With at least 175 million possibilities, it's understandable why states don't have to worry about cutting out those undesirable phrases people come up with for their personalized license plates.Anonymoushttps://www.blogger.com/profile/18153935609499338685noreply@blogger.comtag:blogger.com,1999:blog-15628310.post-50934079293997201282010-09-21T10:04:50.475-04:002010-09-21T10:04:50.475-04:00Just one per vehicle?Just one per vehicle?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-15628310.post-33821803019353843452010-09-21T04:54:36.821-04:002010-09-21T04:54:36.821-04:00Letters = A,B,C....Z = 26
