Wrong!

Explanation:

Kayleen does not understand that each flip of a fair coin is independent of any prior flips. Irregardless if the prior flip was heads, the next flip is unaffected by prior results .

The probability of a head or tail remains the same with each successive flip of the coin.

The next flip has an equal probability (#1/2#) of landing with a head or tail.
