A spinner is divided into 8 sections of equal size. The sections are numbered 1 through 8.

Use this information to determine the probability of the needle landing on:

1.) Section 7
2.) an even numbered section
3.) Section 1, 2, 3, or 4
4.) Section 9
5.) Section 8

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
