Question

A spinner is divided into 8 equal sections where 3 are black, 4 are yellow, and I is red. If it is spun randomly, what is the probability of it landing either on a yellow or a red section?

Answer 1

Given:

A spinner is divided into 8 equal sections where 3 are black, 4 are yellow, and 1 is red.

To find:

The probability of it landing either on a yellow or a red section.

Solution:

We have,

Total number of sections = 8

Black sections = 3

Yellow sections = 4

Red sections = 1

Now,

Either yellow or red sections = 4 + 1

= 5

Now, the probability of it landing either on a yellow or a red section is:

`\text{Required probability}=\frac{\text{Either yellow or red sections}}{\text{Total number of sections}}`

`\text{Required probability}=(5)/(8)`

Therefore, the required probability is
`(5)/(8)`.
