After 10 experiments, not a big deal, but after 10,000, this would have caused me pause. Say, well, why would this happen? I mixed up the bag every time, and there are some different possibilities. Maybe the blue marbles are slightly heavier, and so when you shake the bag up enough, the blue marbles settle to the bottom, and you're more likely to pick a magenta marble. Maybe the blue marbles have a slightly different texture to them, in which case maybe they slip out of your hands or they're less likely to be gripped on, and so you're more likely to pick a magenta. I don't know the explanation. I don't know what's going on in that bag, but if I thought theoretically that the probability should be 1 half, because half of the marbles are magenta, but I'm seeing through my experiments that 80% of what I'm picking out, especially if I did 10,000 of it, if I did this 10,000 times, well, this is going to cause me some pause.
