WebSep 2, 2024 · Rewrite the inequality: Your first instinct might be to cross-multiply: : z) z) Y 0 surely. What if Y 0 only almost surely, i.e. P(Y 0) 1 but technically we don't have surely that 0 (Precisely there are 's s.t. () 0, but they are too small to count)? Well then, we'll use total probability: z Y Now consider the latter term, P(X ≥ Yz ∩ Y < 0). WebWell, one of those rules is called the multiplication property of inequality, and it basically says that if you multiply one side of an inequality by a number, you can multiply the other side of the inequality by the same number. However, you have to be very careful about the direction of the inequality! Watch the tutorial to see how this looks ...
