Question

Cecil solved a theoretical prediction problem, where a spinner would be spun 30 times. She correctly concluded: “The spinner will land on the red section 6 times.” What could the spinner look like? Is there more than one possible solution?

Answer 1

The spinner has 5 equal sections, with one section red.

It can have 5N equal sections, with N sections Red

Explanation:

p(red) = 6/30 = 1/5

1/5 = 2/10

Out of 10 sections, 2 are Red

In general,

It can have 5N equal sections, with N sections Red

Answer 2

6 out of 30 times would be written as

6/30 which reduces to 1/5 which would mean the spinner is divided into 5 different colors.

There could be more than one solution. The spinner could be divided into 10 spaces and red could be 2 of the spaces, or any other multiple of 5s
