Question 1 (9) You now have to design a threshold for the number of trials so that a genuine user that mistypes a password can still try again, but a malicious attacker who is trying to guess that password has a very low chance of being successful. In fact the design criteria is that the probability that an attacker is successful must be less than 1%. For the probability distribution you picked in 1(f), describe how you would go about choosing the threshold and indicate the threshold you have chosen. You can use the space in the code block in 1(f) to do any necessary calculations to help you decide. (2.5 marks)
