The digit 1, 2, ..., n(n > 5) are put at random in a row. (a) Show that the probability that the digits 4 and 5 will be adjacent is 2/n. (b) Find the probability that the digits 4 and 5 will not be adjacent. (c) Find the probability that the digits 4 and 5 will be adjacent or the digits 2 and 3 will be adjacent. That is, find P((4 and 5 adjacent) ∪ (2 and 3 adjacent)).

Question 5# (Combinations, including stars and bars') Problem: How many PINs have digit suam 20? (A PIN is string abcd of 4 decimal digits eg 6806) As a first attempt at answering this: (a) How many different solutions in non-negative integers has the equation a+b+c+d-20? Hint: 20 stars and 3 bars. The count in (a) is much too big for our problem because it includes many solutions that contain non-decimal digits; ie. values of a, b, c or d that...
