A thief steals a smartphone that authenticates its owner using a 4-digit PIN, with no disabling, jailing or exponential back-off for making too many failed authentication attempts. Using Anderson’s formula, what is the probability that an attacker is able to log into the phone within 3 hours? Assume that the thief is able to try one PIN every 2 seconds. (6marks)
