3-In a recent year, 304 of the approximately 300.000.000 people in United States were struck by lightning. The probability that a randomly selected person in the United States will be struck by lightning this year is 0.00000101. Is a golfer reasoning correctly if he or she is caught out in a thunderstorm and does not seek shelter from lightning because the probability of being struck is so small?
