Question

A round spinner is divided into five sections, where the sections do not have the same size. Using the measure of the interior angles, the probability of the spinner landing on any individual space on a spin is calculated and given in the table

Answer 1

Minimum probability is 0.05, so we have to choose n such that expected frequency corresponding to 0.05 probability should be at least 5.

Let n = 5

Expected frequency = n*p = 5 * 0.05 = 0.25 < 5

Let n = 25

Expected frequency = n*p = 25 * 0.05 = 1.25 < 5

Let n = 50

then

Expected frequency = n*p = 50* 0.05 = 2.25 < 5

Let n = 100

then

Expected frequency = n*p = 100* 0.05 = 5 = 5

Thus, for n = 100, we get expected frequency = 5,

Thus, the minimum number of times the spinner should be spun to conduct this test is 100.

What is a probability?

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event.
