Hi,
Take for example the list (L):
John, John, John, John, Jon

We are to presume one item is to be correct (e.g. John in this case), and give a probability it is correct. First (and good!) attempt: MostFrequentItem(L).Count / L.Count (e.g. 4/5 or 80% likelihood)

But consider the cases:
John, John, Jon, Jonny
John, John, Jon, Jon

I want to consider the likelihood of the correct item being John to be higher in the first list! I know I have to count the SecondMostFrequent Item and compare them.

Any ideas? This is really busting my brain!
Thx, Andrew
