A dartboard is made up of concentric circles with the
following radii:
D
Circle A: r = 2 inches
Circle B: r = 4 inches
Circle C: r = 6 inches
Circle D: r = 10 inches
What is the probability that a dart will NOT hit inside the C circle?
(This means it could hit in either the C, B or A circle and be good).
Round your answer to the nearest percent.
(No % sign, just numbers)
