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 - 33.3%
Experimental - 38%

B.
Theoretical - 16.7%
Experimental - 19%

C.
Theoretical - 33.3%
Experimental - 19%

D.
Theoretical - 38%
Experimental - 33.3%

Answer 1

The closest correct answer is C. :)

Answer 2

Theoretical probability = \[\frac{ Number of favorable outcomes }{ Total number of possible outcomes }\]

Answer 3

Oops, that is supposed to be Number of favorable outcomes over the total number of possible outcomes.

Answer 4

Experimental Probability = \[\frac{ Number of times event occurs }{ Total number of trials }\] Not sure why it pushes all the words together. But I think you'll get the point...
