To calculate the probability that a dart thrown at random will hit the bulls eye, we need to compare the area of the bulls eye to the total area of the dart board.
The area of the bulls eye is π(4)^2 = 16π square inches.
The total area of the dart board is π(18)^2 = 324π square inches.
Therefore, the probability is 16π / 324π = 0.0494, which rounded to the nearest tenth is 4.9%.
So the answer is b. 4.9%
