A circular dartboard of radius 1 foot is at a distance of 20 feet from you. You throw a dart at it and it hits the dartboard at some point Q in the circle. What is the probability that Q is closer to the center of the circle than the periphery?
a) 0.75
b) 1
c) 0.25
d) 0.5

  radius of inner dartboard/overall radius of dartboard
  
  ((r/2)^2)/(r^2)=1/4=0.25
