In the statistical sense, yes, it is possible to predict. That is rather similar to the statistician's argument during the briefing for the first 1000 bomber raid over Cologne in May 1942 that predicted only two aircraft would collide, despite the incredible density of aircraft over the target, at any rate compared with modern air traffic control standards! The question asked by the crews was, of course, "_Which_ two aircraft are going to collide?" As it happened, the statisticians were perfectly correct - two aircraft _were_ lost due to collision (together with forty odd losses from other causes - including enemy action) but it was of course no more possible to predict exactly which aircraft were going to collide than it is to predict which specific Mersenne numbers will be prime without actually running LL tests. > >>I ask because I was looking at the mersenne.org website and > >>noticed that it states that on December 6, 2001, the 39th > >>known Mersenne Prime was found.

The actual prediction was that this interval was the interval _most likely_ to contain the _40th_ Mersenne prime.
