Hello all, I think that this is a repost for me, but I am wanting math jokes in part because I do not have many. Ok, here we go. Two probabilists are invited to a seminar in another country. One asks the other if he would like to fly together. His colleague replies "No, I have computed the probability of a bomb being on the plane and it is too high. I have decided to take the bus." So, the day of the flight comes and as the first probabilist is boarding the plane he sees his colleague sitting in a seat. He asks his colleague "Why are you here? I thought that the probability of a bomb being on the plane was too high?" His colleague replies, "Well, I calculated the probability of two bombs being on the plane, and this number is acceptably low. So now I just travel with my own bomb." Ba Dum Chhhh!
