Er, no, unless you assume that repeated flips of the coin in some 
way deform it so as to bias the outcome.

An extended run of heads might lead you to conclude that the coin 
is biased, and so increase your _expectation_ that the next flip 
will also result in a head, but that doesn't alter the actual 
underlying probability.
