Lets say you have a certain number of indicators. Each indicator on it's own own has an 80% chance of being accurate, if you have 5 or 7 different indicators say, how likely is it that the majority would be accurate ?

Thanks.

Overall the majority will be accurate - you have said 80% will be accurate, and 80% is a majority.

Sorry, to clarify, I mean each indicator on it's own is 80% accurate.

Lets say we have 5 indicators that each will say "red" 80% of the time to indicate red, but can also sometimes say "blue" 20% of the time.

What are the chances of 3/5 of them saying "red", what are the chances of all of them saying "blue" ? etc.
