A secret code for a bank vault consists of 2 letters, then 4 digits and then 4 more letters. How many different codes are possible? Answer How many codes are possible if repeating letters and digits is not allowed? Answer: How many codes are possible if repeats are not allowed and the second letter must be 'U' and the third digit must be '6'? Answer: If the wrong code is entered the vault automatically locks and the alarm sounds. Suppose repeating letters and digits are allowed in the code. What is ther probability of a thief breaking into the vault if the thief has no prior knowledge of the secret code? Answer:
