Question

Find the probability that a randomly chosen point inside the figure lies in the shaded region.

  1. fraction numerator 1 over denominator 3 end fraction    
  2. fraction numerator 1 over denominator 2 end fraction    
  3. fraction numerator 3 over denominator 4 end fraction    
  4. fraction numerator 1 over denominator 4 end fraction    

The correct answer is: fraction numerator 1 over denominator 2 end fraction


    we are asked to find the probability that a randomly chosen point inside the figure lies in the shaded region.
    This octagon is divided into 8 equal parts.
    P = fraction numerator N o blank o f blank s h a d e d blank p a r t s over denominator T o t a l blank n o blank o f blank p a r t s end fraction = fraction numerator 4 over denominator 8 end fraction = fraction numerator 1 over denominator 2 end fraction

    Therefore the probability that a randomly chosen point inside the figure lies in the shaded region is 1/2
