The very least is even less than what I wrote: it's the smallest possible overlap between convinced atheists and fengshui believers: (47-(100-61)) = 8% of the population being both.

You can call it common if you want, but again I don't see how you'd get from that to anywhere near "the majority of atheists globally believe in astrology".
