Significantly Decreased Probabilty

A man has been afraid of riding airplane ever since his childhood in fear of that someone will bring a bomb on the plane. He managed years and years to go places avoiding flights.    As time went on, his son grew older, went to college, found a job, got married and settled down on the other coast of the country.  One day, his son called him up.  “Daddy, we just had a new baby and you should come over to see your grandson.”   The 3,000-mile distance made the air travel to be the only viable option for him to see his son.  After struggling for a few days, he went to a psychroic doctor to seek advices.   Understood his concern and thought for a while, the doctor suggested the man to carry one bomb himself to board the plane.   “Why do you ask me to do that?”  The man was surprised about the advice.   “Well, the probability to find one bomb on a plane is about one millionth.”  The doctor showed the patient the FBI statistics.  “Accordingly, the probability to have two bombs on the same airplane will decrease to one trillionth.  That means nearly zero probability and therefore that flight for you to ride will be very safe that way.”
