Why does it makes sense that the products of opposite corners of any rectangle in the multiplication table are equal?
Consider the rectangle in a multiplication table where the left side of the rectangle is in the column for p times table; the right side of the rectangle is in the column for q times table. Also suppose the top of the rectangle is in the row for the r times table and the bottom of the rectangle is in the row for the s times table.Schematically,----p------q----|-------|r---a-----b----|------|----|------|s--c-----dSuppose the numbers in the four corners of the rectangle are a, b, c and d.Thena = pr, b = qr, c = ps and d = qsSo the product of opposite corners aread = pr x qs = pqrsbc = qr x ps = pqrs
What is the describing of the complementary event and find its probability?
Suppose there is an event A and the probability of A happening is Pr(A). Then the complementary event is that A does not happen or that "not-A" happens: this is often denoted by A'.Then Pr(A') = 1 - Pr(A).Suppose there is an event A and the probability of A happening is Pr(A).

What is the difference between the multiplication rule for independent versus dependent events?
Given two events, A and B, Pr(A and B) = Pr(A)*Pr(B) if A and B are independent and Pr(A and B) = Pr(A | B)*Pr(B) if they are not.
Is a crossed rectangle a rectangle?
crossed rectangle is not a rectangle, rectangle have to have 90 degree angles.
How many rectangle has corner?
Every rectangle must have corners otherwise it would not be a rectangle!Every rectangle must have corners otherwise it would not be a rectangle!Every rectangle must have corners otherwise it would not be a rectangle!Every rectangle must have corners otherwise it would not be a rectangle!
