Take five gold coins of variable but unknown imbalance (such that each one has a different probability for heads) and five similar silver coins. Ask N people to toss each coin in sequence and record the number of heads. how can one determine outliers who have special mental powers to determine the outcome i.e. can make every coin turn up heads) Or have at least partial special powers to influence the outcome. How large should N be to have significance? I am not a mathematician. This is a real problem in my research and I would prefer to use a simple program to solve this.

Only my username is MATHEMATICIAN though I am not really a mathematician. Your problem seems to be very complex. Could you please elaborate the problem.

The answer is unknonw, But I'm able to toss 7080% head if I start headup... over 100 runs (keeping and reverting at the end). But who knows if I run 100*10^6 ? It seems question of technique and skill: once you are able to repeat same starting position and technique of launch / catch you can rise lot the number of expected results. So lot depends on the peoples you will choose etc...
