An electron is trapped in a one-dimensional infinite potential well that is 310 pm wide; the electron is in its ground state. What is the probability that you can detect the electron in an interval of width δx = 5.0 pm centered at x = 34 pm? (Hint: The interval δx is so narrow that you can take the probability density to be constant within it.)
