Your password in your company's ERP (Enterprise Resource Planning) System requires exactly eight characters. And each character is one of the of the 26 letters (a-z) or 10 integers (0-9). Let A denote the subset of passwords that begin with a vowel (either, a, e, i, o, u) and let B denote the subset of passwords that end with an even number (either 0,2,4,6, or 8) Suppose a hacker guessed that your password is in event A and B and selects a password at random from this subset. What is the probability that your password is hacked? O a. 1 368 O b. None among the choices O c. 1 5(367) O d. 1 (5) (5) (366)
