    Sherwin throws a dart at this square-shaped target: Part A: Is the probability of hitting the black circle inside the target closer to 0 or 1? Why? Part B: Is the probability of hitting the white portion of the target closer to 0 or 1? Why?

    so the area of the circle and the area of the square must be found. The diameter of the circle is 4 so to find the area we will do A=pir^2 which is A=pi(2)^2 so A=4pi now we have to take the area of the square which is 22^2= 484 so the probability is 4pi/484

    4pi/484 comes out to .026 which is far closer to 0 than it is to 1

    The probability of hitting the white part is 484-4pi/484 =

    this is equivalent to .97 which is far closer to 1 than it is to 0.

    So the probability of hitting the black part is close to 0 and the probability of hitting the white part is close to 1.
