Answer:
If the question states that they are not being replaced, then the answer is 1/8
If the question states that they are being replaced, then the answer is 1/9
Step-by-step explanation:
3/9 x 2/8 = 1/8
3/9 x 2/9 = 1/9

The light's coverage area is given mathematically as i.e. Area=
Given that a lighthouse casts a revolving beam of light as far as they peir and asked the area is covered.
The revolving beam of light covers the whole space i.e entirely 360°
I.e. it forms a circle-like region
Area of circle =  { where r is the radius of circle}
{ where r is the radius of circle}
Let's assume the distance traveled by light as "d"
as it forms a circular region, it forms a circle of radius "d"
Mathematical connection i.e. area of the region
⇒area of circular region= {where d is the radius of region}
 {where d is the radius of region}
