Explanation & Answer

Thank you for the opportunity to help you with your question!

Toss the coin twice. 

Let TH, HT and TT correspond to the three choices. 

And if you get HH, just repeat (so it takes 8/3 tosses on average).

Please let me know if you need any clarification. I'm always happy to answer your questions.
