1/2

probability of getting heads is always 1/2, assuming we are flipping a single coin.

one flip does not affect the probabilility of the second flip, or the third flip, or any other flip

$\frac{ C }{ 200 } So narrow \it down get \it alone.$

now, if the question had asked, "what is the probability of getting 200 heads in a row" that question would be a bit different

$\frac{ C }{ 200}=\frac{ 1 }{ 2}$

$\frac{ C }{ 200 }$$-\frac{ C }{ 100 }$ $C=1$

$\frac{ 1 }{ 2 }$
