Question

Michaela’s class used a spinner that has 6 spaces of equal area in which the arrow can land. The areas are numbered 1, 2, 3, 4, 5, and 6. The students spun the arrow 500 times and recorded the number of the space in which the arrow landed for each spin. Which is the best prediction of the number of times the spinner landed on a space numbered greater than 4?

Answer 1

The number of times the spinner landed on a space numbered greater than 4 = 167

Explanation:

Step 1 :

Given,

Number of equal area spaces in the spinner = 6

Number of times the spinner was spun = 500

We need to find the number of times the spinner landed on a space numbered greater than 4

Step 2 :

Total number of outcome = 6

Favorable outcomes are = Numbers greater than 4 = 5,6

Total number of favorable outcome = 2

Therefore Probability that the spinner will land on a number that is greater than 4 is
`(2)/(6)` =
`(1)/(3)`

The number of times that the spinner landed on a space numbered greater than 4 = 500 ×
`(1)/(3)` = 166.67 = 167 (rounded off to the nearest integer)

Step 3 :

Answer :

The number of times the spinner landed on a space numbered greater than 4 = 167
