There were 4 people sitting in a row, truing to win $50.00 from a riddle.
The one in front was wearing a red hat.
The second from the front was wearing a blue hat.

The last was wearing a blue hat and is blind-folded.
Each of them were informed that they are all wearing a hat,
the last person is blind-folded and that there are 2 red and 2 blue hats. If they can guess the
colour of their hat, then they win the prize.
