The Texas lawsuit says there is a 1 in a quadrillion chance that Biden beat Trump in one of the 4 states named in the suit. This means there is 1 chance in a quadrillion to the 4th power of simultaneously winning all 4. 1 in a quad to the 4th equals 1 in 10 to the 60th. For some perspective space.com cites a scientist who estimates there are 10 trillion galaxies in the universe multiplied by 100 billion stars in a galaxy (the Milky Way.) This gives us 1 x 10 to the 24th. If we multiply that number by the number of seconds in the history of the universe in order to get a bigger number we get 10^24 x 10^17= 10^41. If we used the fastest existing computer which runs at 415 petaflops or 4.15 x 10^15 and ran 10^15 elections every second for the history of the universe (10^17) in every star system in the universe (10^24) we would get 1 chance in 10^56. So if we had an election in every star system in the universe every second in the history of the universe using the fastest computer in the world we would only have a 0.1% chance of all 4 states electing Joe Biden. TL;DR History of the Universe x All the Stars in the Universe x Fastest Computer in the World = 1 chance in a thousand of Biden's victory.
