Guess simultaneously, color of your hat, no passing allowed












0












$begingroup$


1000 logicians standing in a circle are blindfolded and a hat of either black or white color is placed on each person's head. The blindfolds are then removed and each person can now see everybody's hat color but his own. After exactly one minute, they all have to simultaneously guess their own hat color.



No communication in any form is allowed after the hats have been placed. However, before the hats are placed, the logicians are allowed to gather and devise a strategy for maximising the number of correct guesses.



Questions :
1) What should be their strategy to get the maximum guaranteed
correct guesses ?



2) Had the total number of different hat colors been three instead
of two, then what strategy should they have devised to get the
maximum guaranteed correct guesses ?
