What is the probability that a randomly thrown dart hits the square board in shaded region
(Take `π = (22)/(7)` and express in percentage)

Find the probability of the dart hitting the board in the circular region B (i.e. ring B)

From the given figure. Find the probability of the dart hitting the dart board in circular regions A.

Without calculating, write the percentage of probability of the dart hitting the board in circular region C (i.e. ring C).
