UnBiased coin

We have a weighted coin that shows a Head with probability $p$ and tails with $1-p$, $(0.5<p<1)$. How to define two equally likely events using this coin?

Each event is a function of the outcomes of one or more coin tosses. For example, we can toss 2 times and define Event1 as [HH, TT] and Event2 as [TH, HT].
