That isn’t to say that there’s no competition. Zigbee was the big dog before Thread came out, and major brands like Philips Hue still use Zigbee to this day for some of their older hubs and lights. That’s changing as Philips Hue has already committed to supporting Matter over Thread anyway, but products that don’t use Matter or Thread still exist on the market.
The same decomposition works in higher dimensions. For NNN random points on a sphere, the probability they all lie in a hemisphere is also N/2N−1N / 2^{N-1}N/2N−1. The argument is identical: anchor a hemisphere at each point, observe that each event has probability 1/2N−11/2^{N-1}1/2N−1, and verify that at most one anchor can work (the complementary cap is at least a full hemisphere, so no other anchor's hemisphere can straddle it). TODO: If I figure out how to add 3d visualizations to this website, I'll cover the 3D case
