Question

The spinner shown has congruent sections. The spinner is spun 63 times. What is a reasonable prediction for the number of times the spinner will land on a section that is shaded red?​

Answer 1

36 times

Explanation:

Given

`Red = 4`

`Total = 7`

`n = 63`

Required

Predicted number of times to land on red

First, we calculate the probability of landing on red

`Pr = (Red)/(Total)`

`Pr = (4)/(7)`

The predicted number of red is the =n calculated as:

`Red = Pr * n`

`Red = (4)/(7)*63`

`Red = 4 * 9`

`Red = 36`
