Re: tossing a coin is not a random process

[Dennis Roberts]

A key "may be" in the minting process ... I heard once at a conference 
where a demo was done .. lining up coins on edge and pounding the table ... 
that the p is not 50/50 for H and T to land face up ... that there is a 
slight bevel to the edge (not noticeable by eye) that makes ejecting from a 
mold easier

Is there any truth to this? I have no idea ... I just pass it along ...

In a local radio presentation, one mathematician has shown that tossing a 
coin is not always random. If one positions the head up when tossing, 
he/she will more likely end up with the head more than 50% (to be exact 
51%) of the time. What do the stat gurus say about this?  Cheers. Siddeek
