A password generator creates a 10-character case-sensitive alphanumeric (a-zA-Z0-9) password keyed by pseudo-random number generator that has deterministic output based on a 32-bit seed (e.g., a 32-bit integer) provided by the user.  How many passwords are possible?  If it takes .0001 seconds to check a password, what will the average length of time be for a successful brute force attack?
