A circular dashboard of radius 2.0 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?
0.75
0.25
1.00
0.50

• 1/4= 0.25 .
  
  If we divide circle area in 2 parts by drawing a circle of radius 1/2 of original radus ,
  as area of circle Q closer to the center of the circle than the perphery is one fourth of total area.
