In an experiment, a large number of electrons are fired at a sample of neutral hydrogen atoms and observations are made of how the incident particles scatter. The electron in the ground state of a hydrogen atom is found to be momentarily at a distance a0/2 from the nucleus in 4 300 of the observations. In this set of trials, how many times is the atomic electron observed at a distance 2a0 from the nucleus?
