Fun thread to read. Fun to think that somebody really could think you can fool true 50/50 odds, without messing with the odds themselves. I also wonder why MacGyver (suitable nick there!) asks if he was conned, when clearly he knows tricks and the facts better than anybody else. But still, what I wanted to say is thanks, I really enjoyed it.
...And claiming you get a coin same side up 51% of the time (of course based on minor assumptions of all coins in the world behaving the same and all people tossing the the same as some lab "robot" etc). That was a hoot! Of course, now that it has been "scientifically proven", nobody can disapprove of it without a PhD.
for the fun the fun of it, just one more time:
10 tosses, the "tossee" calling heads 7 times, but changing the call for the last three times, to keep the tosser from double-guessing
... goes like this:
1.heads - 50/50 change of heads - chance of winning: .5
2.heads - 50/50 change of heads - chance of winning: .5
3.heads - 50/50 change of heads - chance of winning: .5
4.heads - 50/50 change of heads - chance of winning: .5
5.heads - 50/50 change of heads - chance of winning: .5
6.heads - 50/50 change of heads - chance of winning: .5
7.heads - 50/50 change of heads - chance of winning: .5
8.tails - 50/50 change of heads - chance of winning: .5
9.tails - 50/50 change of heads - chance of winning: .5
0.tails - 50/50 change of heads - chance of winning: .5
