Let A be a collection of sets, then We defined A’ = Union of all elements of A. Definition: If A = NOT the union of C and D , where C and D are non empty sub-collection, such that C’ intersect D’ = empty Then A is coherent. Prove: if A is coherent then A’ is connected (i.e A’ is not the union of two separated sets in standard topology)

Provide an example 1) A nested sequence of closed, nonempty sets whose intersection is empty. 2) A set A that is not compact and an open set B such that A ∪ B is compact. 3) A set A that is not open, but removing one point from A produces an open set. 4) A set with infinitely many boundary points. 5) A closed set with exactly one boundary point

suppose that for every pair of disjoint closed sets A and B of X there exist a countinous function f:X-> {0,1} such that f(A)={0} and f(B)={1}. show one point set is closed in X.

Give Examples (this is complex analysis): (a.) First characterize open and closed sets in terms of their boundary points. Then give two examples of sets satisfying the given condition: one set that is bounded (meaning that there is some real number R > 0 such that |z| is greater than or equal to R for every z in S), and one that is not bounded. Give your answer in set builder notation. Finally, choose one of your two examples and...

give an example of a discrete random variable X whose values are integers and such that E(X) = infinite. Prove that E(X) = infinite for your example. (hints: if you will be paid 2^k dollars for the kth head when you flip a fair coin., the expected value is infinite...) Or give other easy examples.
