    This is the concept of the probability and statistics. To get the probability of hitting the inner circle we proceed as follows;

    P (inner square) = [area of inner circle]/[area of outer square]

    area of inner square will be:

    Area=length*width

    Area=4*4=16 m^2

    Area of outer square:

    Area=7*7=49 m^2

    thus;

    P (hitting inner square) = 16/49=0.3265=32.65%
