Question

Four spinners with distinct sections of equal area are spun 40 times. Which spinner is most likely to produce actual results closest to the predicted results?
A)a spinner with 2 sections

B)a spinner with 5 sections

C)a spinner with 8 sections

D)a spinner with 10 sections

Answer 1

A because you are only spinning it 40 time and you only have two options. 

Answer 2

Answer:

It is given that , Four spinners with distinct sections of equal area are spun 40 times.

We want, theoretical Probability should be equal to experimental probability.

The Spinner with least Division and maximum number of Spun will produce result equivalent to Theoretical probability.

Here , in the problem there are four spinners, one having 2 cross sections, second having 5 cross sections, third having 8 section, and fourth having 10 section.

So, Minimum number of Section is in Spinner A , which is equal to 2, probability of each section being equal to $\frac{1}{2}$, Spinner having 5 cross sections,probability of each section being equal to $\frac{1}{5}$,third spinner, having 8 section,probability of each section being equal to $\frac{1}{8}$,fourth spinner having 10 section, probability of each section being equal to $\frac{1}{10}$,.

To get the result that is experimental probability equal to theoretical probability, the number of trials should be as large as possible to get the result equal to theoretical probability.

Option A: a spinner with 2 sections , is most appropriate choice among four options.
