The area of the entire square board is 10x10 = 100 square cm. The area of the bulls-eye square is 4x4 = 16 square cm.
The probability that the coin lands entirely within the bulls-eye is the ratio of the area of the bulls-eye to the area of the entire square board.
Therefore, the probability is 16/100 = 4/25. So the answer is 4/25.
A square board with side length 10 cm is marked with a bulls-eye shaped like a smaller square in the center, with side length 4 cm. A coin is tossed on the board. What is the probability the coin lands entirely within the bulls-eye?
