Scoring a hole-in-one is the greatest shot a golfer can make. Once 55 professional golfers each made holes-in-one on the 8th hole at the same golf course at the same tournament. It has been found that the estimated probability of making a hole-in-one is 12856 for male professionals. Suppose that a sample of 55 professional male golfers is randomly selected. What is the probability that none of these golfers make a hole-in-one on the 13th hole at the same tournament?
