Electron-in-box. What is the probability of finding an electron in the central third of the box. Assume that the electron is in its ground state. $\begin{array}{l}?{\sin }^2(ax)dx=\frac{x}{2}?\frac{\sin (2ax)}{4a}\\ ??{?}^2=2/L{\sin }^2\left(\frac{n?}{L}x\right)\text{ particle-in-bo }\end{array}$ Consider the last problem, what would be the probability for a classical particle in the same interval. Provide a detailed calculation.
