Consider the situation given below:

Let a regular polygon be inscribed in a sphere such that its circumcentre is at a distance r from the centre of the sphere of radius R. A point source of light is kept at the centre of the sphere. How can we calculate the area of the shadow made on the surface of the sphere.

I tried to use the relation: Ω=SR2

But of course that is the case when a circle would be inscribed. So can I somehow relate it for any general polygon?

Since the events are dependent, the probability of occurrence of event B will impact the probability of occurrence of event A. So we will be using the formula of conditional probability to find P(A ∩ B).

$P(A|B)= \frac{P(A*B)}{P(B)} \\ \\ 
P(A*B)=P(A|B)P(B)$

Here P(A*B) indicates P(A ∩ B).

Using the values, we get:

P(A ∩ B) = 0.25 x 0.4 = 0.1

Thus, option A gives the correct answer.
