Assume that to log in to a computer network a password must be entered. A hacker who is trying to break into the system randomly types one password every 3 seconds. If the hacker does not enter a valid password within 2 minutes, the system will not allow any further attempts to log in. The password consists of any sequence of two letters and three digits. Case does not matter for the letters. Thus, B12q5 and b12Q5 are considered the same password. What is the probability that the hacker will be successful in discovering a valid password? (Hint: If E is an event, then P(Upper E prime)equals1minusP(E), where Upper E prime is the complement of event E.)
