Unbiased Coin

Easy probability interview practice: Unbiased Coin.

We have a weighted coin that shows Heads with probability $p$ and Tails with probability $1-p$, where $0.5 < p < 1$. How can you 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}.
