a 10 - 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 two meters of either end . the probability of this is 4 / 10 = 2 / 5 . the answer is d ."
divide(square_perimeter(4), 10)
