The given identifier string is not relevant to the question. The probability of the first subject being robbed is 1/25, and the probability of the second subject being robbed is also 1/25 (assuming that the chance of being robbed is independent of each other). Therefore, the probability of both subjects being robbed is (1/25)*(1/25) = 1/625, which is approximately 0.0016 or 0.16%. None of the answer choices are correct except for D, which is the closest with 6.4%.
