1. For spinning the spinner one time A could be {1, 2, 3} or, A = {1, 2, 3, 4} is possible.

   What is a set?

   The set is mathematical model for a collectionof different things;a set contains elements or members, which can be mathematical objects of any kind: numbers, symbols, points in space, lines, other geometrical shapes, variables or even other sets.

   The given spinner is divided into 8 equal sized sections, so the possible set can be written as-

   S = {1, 2, 3, 4, 5, 6, 7, 8}

   Now the possible subsets can be-

   Even numbers = {1,3,5,7}

   Odd numbers = {2,4,6,8}

   Any number or group from 1 to 8, inclusive

   Hence for spinner the spinner for one time, suppose A be the possible set. Then,

       A could be {1, 2, 3}.

   or, A = {1, 2, 3, 4}.

   where A is the subset of S.

   Hence, For spinning the spinner one time A could be {1, 2, 3} or, A = {1, 2, 3, 4} is possible.
