The 16th flip will have the same probabilities as any other flip.

First you have to decide whether the events are dependent or independent. In other words, does the outcome of previous event could evoke a change in the following event?
So first answer this question.
If on the first flip, the outcome was white, will it change the probabilities of the outcomes of next event? The answer is No. The probability will remain same 50:50 for each event. So we can also conclude that on 16th flip no matter the outcomes were in previous flip, the probability landing white will remain 0.5
