According to the website wordfinder.yourdictionary.com, the English language has approximately 20,000 six-letter words. a) Assume that a password must be at least 8 characters long and include at least 1 digit and at least 1 special character. If people form their password by taking an English word of exactly 6 letters (assume that this password is not case-sensitive) and then adding (in either order) a digit and a special character (eg flames#1), how many passwords would be possible? (Hint: Find the number of passwords with 6 letters followed by a digit and a special character, then exchange the order of the last two characters.) b) How does your answer change if we assume that we still have a 6 letter word, but now we assume that both the digit and the special character can be inserted into the word in any position (e.g. fla#me1s)?
