4. (1 pts) A quanton's wavefunction $\psi(x)$ at a certain time passes through zero at a certain position $x_0$. If we do an experiment to locate the quanton at that time, is the probability of getting the result $x_0$ less that (or equal to) the probability of getting any other result, or does this depend on the shape of the wavefunction at other position? Explain your response.
