Better Stars and Worlds

I'm going with the cube root of 1/2, or about 79.37% of systems have planets.
3 planets in our sample star system.
3,844,755 planets out of a million 'draws'.
This is a small system, half the size of our own, but we do think that Sol is an outlier... About one fifth of systems never develop planets and about the same fraction, a little less, have one planet, while roughly half of all systems have less than three, or three or more, planets. About half of the latter have less than six, or six or more, and so on. Each iteration of multiplicity is roughly 80% less likely. About 1% of those systems with more than one planet have a hot jupiter and 10% have a Jupiter mass analog, of which roughly a quarter have one with low eccentricity and a quarter of those have no super Earths, less than 1%.
