Larry chooses a unit square at random inside a 4x4 square, whose sides are parallel to the 4x4 square. Laura also chooses a unit square at random, whose sides parallel to the 4x4 square. Find the probability that Larry's and Laura's square intersect.
In the question, does it mention whether or not Larry and Laura's squares must be different? What if they choose the same unit square? I think that part of the question is very unclear.
Yeah. I agree. I don't get the part where is says, "parallel". In a 4*4, how is that even possible?
