The probability that the result is green - tail is 1/6.
Spinner has three colors that are  red, green and yellow and coin has two sides that are  head or tail.
<h3>What is the formula for probability?</h3>
Divide the number of events by the number of possible outcomes
The sample space is, In total there are 6 ways to combine different colors with coin sides.

Answer:

Step-by-step explanation:
Given f(x)=
We have to find 
In order to find  we have to make x as the subject of the formula
 we have to make x as the subject of the formula
Let us assume f(x)=y
⇒
Subtracting both sides by 5


Dividing both sides by 2

⇒
Now substituting y with x 
we have 
Now 
=
So option (ii) is correct
