Answer:
The probability that a randomly selected point within the circle falls in the red shaded area is p=0.75.
Step-by-step explanation:
We have to calculate the probability that a randomly selected point within the circle falls in the red shaded area.
This probability can be calculated as the quotient between the red shaded area, that is a regular pentagon inscribed in the circle, and the area of the circle.
We start by calculating the area of the circle:

Then, we can calculate the area of the pentagon as:

Then, we can calculate the probability p as the quotient between the areas:
