Assuming a scenario where the Khewra Salt Mines' annual salt production witnesses a stochastic fluctuation modeled by a Wiener process with drift $\mu = -50,000$ tons and volatility $\sigma = 200,000$ tons, what is the probability that the salt production will drop below 600,000 tons within the next year, given the current production is 850,000 tons?

  • Approximately 45.2%
  • Approximately 30.9% (correct)
