A spinner has eight congruent sections numbered 1 through 8. Josh made 50 spins of this spinner and recorded the outcomes in this table.

Outcome Number
1 5
2 8
3 6
4 7
5 4
6 5
7 8
8 7

What is the theoretical probability of the spinner stopping on 7? What is the experimental probability of the spinner stopping on 7?

A.
Theoretical - 6.25%
Experimental - 8%

B.
Theoretical - 12.5%
Experimental - 8%

C.
Theoretical - 12.5%
Experimental - 16%

D.
Theoretical - 16%
Experimental - 12.5%

It is B because it is not asking for what the next number will be so experimental is 8% and out of 50 spins it is 6.25 so multiply it by 2 and it is 12.5. Hope this helped:)
