Aspinner is divided into eight equal-sized sections, numbered 1 to 8, inclusive. what is true about spinning the spinner one at a time? check all that apply. 1. s={1,2,3,4,5,6,7,8} 2. if a is a subset of s, a could be {1,2,3} 3. if a is a subset of s, a could be {7,8,9} 4. if a subset a represents spinning a number less than 4, it’s sample space is a={1,2,3,4} 5. if a subset a represents the complement of spinning an odd number, it’s sample space is a={2,,4,6,8}

1,2 and 5 are true

Step-by-step explanation:

We are given that a spinner is divided into eight equal sized sections and numbered 1 to 8

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

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

It is true because the sample space=S={1,2,3,4,5,6,7,8}

2.If A is a subset of S,A could be {1,2,3}

It is true because if A is a subset of S then all element of set A should be in S.

3.If A is a subset of S, A could be {7,8,9}.

It is not true because if A is a subset of S then all element of set A should be in S and 9 does not belongs to S.

4.If a subset a represents spinning a number less than 4, it's sample space is A={1,2,3,4}

It is not true because A ={1,2,3}

5.If a subset A represents the complement of spinning an odd number, it's sample space is A={2,4,6,8}

Odd number={1,3,5,7}

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

Hence, it is true.
