Do quantum uncertainties differ in any essential way from the uncertainty in a coin flip, and why or why not?
A) With sufficient information, a coin flip's outcome can be predicted, but no amount of information can remove quantum uncertainties.
B) You can make money with coin flips but you can't make a red cent out of quantum theory.
C) They don't differ in any essential way--both uncertainties are inherent in nature and cannot be removed by additional information.
D) With sufficient information, quantum uncertainties can be removed, but no amount of information can make a coin flip predictable.
E) They don't differ in any essential way--both are a consequence of the observer's insufficient information and can be removed by obtaining additional information.
