Step 1: See the given figure and analyse the given information

             GIVEN: A game of chance spinning an arrow,which come to rest pointing

               any of the number 1,2,3,4,5,6,7,8


             So, total number of outcomes = 8


Step 2: Determine the probability that it(arrow) will point at a number greater than 2

              List out the numbers greater than 2 = {3, 4, 5, 6, 7, 8}

              Favourable outcomes of pointing a number greater than 2  = 6


          The probability of pointing a number greater than 2  = \frac{\text{Favourable outcome}}{\text{total number of outcomes}}


                                                                                                 = \frac{6}{8}=\ \frac{3}{4}


Step 3: Find the probability that it(arrow) will point at a number less than 9

               List out the numbers less than 9 = {1, 2, 3, 4, 5, 6, 7, 8}

               Favourable outcomes of pointing a number less than 9 = 8

       The probability that arrow will point at a number less than 9 = \frac{\text{Favourable outcome}}{\text{Total number of outcomes}}\

                                                                                                     = \frac{8}{8}

                                                                                                     = 1
