Question

Henry is going to color a spinner with 8 equal-sized sections.Three of the sections will be blue and 5 of the sections will be purple. Is this spinner fair? If so explain why. If not explain how to make it a fair spinner

Answer 1

Answer:

The spinner is not fair

Step-by-step explanation:

Given

$Sections = 8$

$Blue = 3$

$Purple = 5$

Solving(a): Is it fair?

The spinner is not fair because the probability of an outcome of Blue does not equal the probability of obtaining Purple.

i.e.

$P(Blue) = \frac{3}{8}$

$P(Purple) = \frac{5}{8}$

$\frac{3}{8} \ne \frac{5}{8}$

Solving (b):

To make it fair, the blue sections and the purple sections must be made equal (4 each)
