Sample space (S) = {1, 2, 3, 4, 5, 6, 7, 8}
∴ n(S) = 8
i. Let A be the event that the spinning arrow comes to rest at 8.
ii. Let B be the event that the spinning arrow comes to rest at an odd number.
iii. Let C be the event that the spinning arrow comes to rest at a number greater than 2.
iv. Let D be the event that the spinning arrow comes to rest at a number less than 9.
∴ D = {1, 2, 3, 4, 5, 6, 7, 8}
