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? Select three options.

S = {1, 2, 3, 4, 5, 6, 7, 8}
If A is a subset of S, A could be {1, 2, 3}.
If A is a subset of S, A could be {7, 8, 9}.
If a subset A represents spinning a number less than 4,then A = {1, 2, 3, 4}.
If a subset A represents the complement of spinning an odd number, then A = {2, 4, 6, 8}.

Answer 1

The three true statements are:
- S = {1, 2, 3, 4, 5, 6, 7, 8}
- If A is a subset of S, A could be {1, 2, 3}
- If a subset A represents the complement of spinning an odd number, then A = {2, 4, 6, 8}

Reasons: {1,2,3} is a subset of S; the complement of odd outcomes is the even outcomes {2,4,6,8}. The statement "{7,8,9}" is not a subset (9 ∉ S), and "numbers less than 4" should be {1,2,3}, not {1,2,3,4}.
