Same Topic:

1. For a finite, equiprobable sample space S, show that

P(A|B) = |A ∩ B| |B| , for any two events A, B.

2. Use the result in problem 2 to find P(A|B) where |A| = 25, |A − B| = 15, and |B − A| = 10.

Note the use of the result from 2 allows us to compute this conditional probability without actually knowing the size of our sample space.

Let X be a topological space with topology T = P(X). Prove that X is finite if and only if X is compact. (Note: You may assume you proved that if ∣X∣ = n, then ∣P(X)∣ = 2 n in homework 2, problem 2 and simply reference this. Hint: Ô⇒ follows from the fact that if X is finite, T is also finite (why?). Therefore every open cover is already finite. For the reverse direction, consider the contrapositive. Suppose X...
