Question

A spinner has three congruent sections numbered 1, 2, 3. Yolanda made 50 spins of this spinner and recorded the outcomes in this table.

Outcome Number
1 15
2 19
3 16

What is the theoretical probability of the spinner stopping on 2? What is the experimental probability of the spinner stopping on 2?

A.
Theoretical - 38%
Experimental - 33.3%

B.
Theoretical - 33.3%
Experimental - 19%

C.
Theoretical - 16.7%
Experimental - 19%

D.
Theoretical - 33.3%
Experimental - 38%

Answer 1

theoretical is what you expect will happen. Probability of 2 P(2) = 1/3

experimental is what actually happens...

P(2) = 19/50

so now change both to percentages for the correct answer

Answer 2

And B is incorrect

Answer 3

Basicly D.
