an 11 - meter long wire is cut into two pieces . if the longer piece is then used to form a perimeter of a square , what is the probability that the area of the square will be more than 4 if the original wire was cut at an arbitrary point ?
the longer wire will form a square with an area more than 4 if the wire is cut at a point within three meters of either end . the probability of this is 6 / 11 . the answer is e .
multiply(const_2, divide(subtract(11, square_perimeter(sqrt(4))), 11))
