Question

A spinner is divided into eight equal-sized sections, numbered from 1 to 8, inclusive. What is true about spinning the spinner one time

1. thongdat2
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.
