10. An atom of Uranium-238 is unstable and will eventually decay (i.e., emit a particle and turn into a different element). Given an atom of Uranium-238, the time elapsed until it decays, in years, is modeled as an Exponential random variable with parameter 1 = 0.000000000155. How many years must pass for there to be a 50% chance that the Uranium atom decays?
