More accurately, if you randomly select a company ex post from the sample used to make that headline, the probability of said company having been sold for 1B USD is 0.0000006. With the same conditions, the probability of the sperm that made you getting to the egg, however, was in the interval [0.000000001, 0.00000002]. This, by the way, means the probability of this particular combination of unique human beings alive today is somewhere around 1e^(-1.28e^11) - that is a "0." followed by approximately 128 billion zeros before you hit another number. The probability is so small that writing it out at one digit per second, without sleeping, would take approximately 4000 years. And yet here we all are. Don't make the mistake of thinking that any of that actually means anything beyond what it literally says.
