The probability that a male professional golfer make a hole-in-one is 1/2780. Suppose 10 professional male golfers play the sixth hole during a round of golf. Let Y represent the number of these 10 men who make a hole-in-one on the sixth hole. Calculate the probability that none of the 10 golfers makes a hole-in-one on the sixth hole. (Round your final answer to the ten-thousandths place.)
