A game of chance consists of spinning an arrow which comes to rest pointing at one of the numbers `1,\ 2,\ 3,\ 4,\ 5,\ 6,\ 7,\ 8` (See Fig. 131), and these are equally likely outcomes. What is the probability that it will point at (i) 8? (ii) an odd number? (iii) a number greater than 2? (iv) a number less than 9?
