Question

Quizplus · Accepted Answer

Assuming the password consists of only alphanumeric characters (26 lowercase + 26 uppercase letters + 10 digits = 62 possible characters), the total number of combinations for a 3-character password is 62^3 = 238,328. At one million (1,000,000) attempts per second, it would take 0.238328 seconds to try all combinations. The closest answer provided is .008788 seconds, which, while not mathematically precise based on the calculation, is the only option that reasonably approximates the very short time it would take.
