Question

A spinner is divided into 5 sections.You spin the spinner once. there are 2 parts in the white section and 3 parts in the dark.

* Find the probability that the spinner lands on a white section.

*Find the probability that the spinner lands on a dark section

Answer 1

White: 2/5

Dark: 3/5

Explanation:

There are 5 sections and there are 2 white spots and 3 dark spots.

So, 2 out of the 5 sections are white which is 2/5 and 3 out of the 5 sections is dark which is 3/5.

Answer 2

• The probability that the spinner lands on a white section is
  `(2)/(5)` .
• The probability that the spinner lands on a dark section is
  `(3)/(5)` .

Explanation:

Given : The total number of sections = 5

The number of white sections = 2

The number of dark sections =3

Now, the probability that the spinner lands on a white section is given by :-

`\text{P(white)}=\frac{\text{Number of white sections}}{\text{total sections}}\\\\=(2)/(5)`

Now, the probability that the spinner lands on a dark section is given by :-

`\text{P(dark)}=\frac{\text{Number of dark sections}}{\text{total sections}}\\\\=(3)/(5)`
