When I open a bank account I am allocated a 4-digit personal identification number (which may begin with one or more zeros) at random. (a) What is the cardinality of the sample space for this experiment? (b) By computing the cardinality of each of these events find the probability that: (i) Every digit of my number is even; (ii) My number is palindromic (reads the same forwards as backwards); (iii) No digit of my number exceeds 7; (iv) The largest digit in my number is exactly 7.
