Researchers from a data analysis firm have found that the three most popular combinations --
1234, 1111, and 0000 -- account for close to 20 per cent of all four-digit passwords. The researchers
also found that every four-digit combination that starts with 19 ranks above the 80th percentile in
popularity, with those in the upper 1900s coming in the highest. Also quite common are
combinations in which the first two digits are between 01 and 12 and the last two are between 01
and 31.
If the statements above are true, which of the following must be true?
(A) The password 1922 will most likely be less popular than 1981
(B) The password 0123 will most probably be more common than 2331
(C) If a password was to be selected from a random list of 100 four digit passwords, there is a very high possibility that it will be 1234, 1111, or 0000
(D) One out of three four digit passwords will be 1234, 1111, or 0000
(E) Passwords starting with 19 are more popular than those starting with 21
