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.

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