## Unlikely Events Can Happen If There Are Enough TrialsSuppose an event has one in a trillion (
which is the probability of the event p.) For p = 10
the probability of the event ^{-12}not happening after a trillion
trials is 0.37. For 100 trillion trials the probability of the event not
happening is 0.37 or ^{100}6.
Therefore the event is very likely to happen in 100 trillion trials.^{-44}There are 100 billion galaxies in the universe, each having over a billion
stars. Therefore the number of stars exceeds 10,
the sheer size of the universe suggests that it is highly likely to happen in other planets besides
the earth. Of course such planets maybe many light years away, so we may never know about them.^{-18} |
