For $50? College students have done much weirder and stupider stuff for less money than flipping a coin twice and answering a straightforward T/F question, even if it were twenty questions. The technique has been around for a long time. You should consider it a solved problem. Finally googled the names. I also discovered the original formulations do it with only one coin flip (or one roll of a die). http://en.wikipedia.org/wiki/Randomized_response http://en.wikipedia.org/wiki/Randomized_response http://en.wikipedia.org/wiki/Unmatched_count http://en.wikipedia.org/wiki/Unmatched_count
