I was trying to understand Bells theorem and I found this site http://www.upscale.utoronto.ca/PVB/Harrison/BellsTheorem/Analogy.html easy to understand. I found the "The Second Analogy: More Boxes" in it easy to grasp. But one thing I didn't understand in it, where it uses the word random and expect all possible setting occur equally. Like, here it says, "But the switch settings are made at random, so we expect each of the six possible results in the above table to occur with equal frequency. So both lights flash the same color one-third of the time." Here when we say the switch setting are random, then how is it, that all possible setting occur equally. When it is random, it is possible, only one switch setting can occur all the time OR how is it that all possible setting occur equally? Thank you.
