Why is the energy distribution of beta rays continuous?                                Or Why do all the electrons emitted during beta decay not have the same energy?           

Answer:

                In a \[\beta \] -decay, particles like antineutrinos are also emitted along with electrons. The available energy is shared by electrons and antineutrinos in all proportions. Electron's energy is no longer fixed. Hence energy distribution of \[\beta \] -rays is continuous.
