Question

What is the probability that the spinner lands on blue?

Answer 1

Concept:

The total number of angles in a circle is

`\begin{gathered} =360^0 \\ =120^0+60^0+180^0=360^0 \end{gathered}`

The angle of the sector that represents blue is

`=60^0`

To calculate the probability, we will use the formula below

`\begin{gathered} P(\text{blue)}=\frac{n(\text{blue)}}{n(S)} \\ n(\text{blue)}=60^0,n(S)=360^0 \\ P(\text{blue)}=\frac{n(\text{blue)}}{n(S)}=(60)/(360) \\ P(\text{blue)}=(1)/(6) \end{gathered}`

Hence,

The final answer is = 1/6
