the left-hand-side topology. Endow the plane with the product topology determined by these two

topologies.

Let n be a positive integer and p and r two real numbers in the interval (0,1). Two random variables X and Y are defined on a the same sample space. All we know about them is that X∼Geom(p) and Y∼Bin(n,r). (In particular, we do not know whether X and Y are independent.) For each expectation below, decide whether it can be calculated with this information, and if it can, give its value (in terms of p, n, and r)....

Consider two dice which each only have the numbers one, two and three on their faces, such that each number appears on two faces. One rolls these dice, and let X be the face value of the first dice, and Y be the face value of the second dice. We define W = X + Y and Z= X-Y. 1. Compute the joint probability mass function of W and Z. 2. Are W and Z independent? 3. Compute E[W] and...

(a) This exercise will give an example of a connected space which is not locally connected. In the plane R2 , let X0 = [0, 1] × {0}, Y0 = {0} × [0, 1], and for each n ∈ N, let Yn = {1/n} × [0,1]. Let Y = X0 ∪ (S∞ n=0 Yn). as a subspace of R 2 with its usual topology. Prove that Y is connected but not locally connected. (Note that this example also shows that...

Consider our usual setting with two goods (food and clothing) and two inputs (capital and labor). Units of labor and capital respectively needed to produce one unit of food are given by LF = 4, KF = 1, meaning that you need 4 units of labor and 1 unit of capital to produce 1 unit of food. The input requirements to produce one unit of clothing are given by LC = 1, KC = 2. Denote LC and KC as...

Consider two hypothetical dice, each of eight sides. Both dice also share the same numbers recorded on the eight sides of the dice: 6, 7, 10, 11, 14, 18, 24, 28 One of the dies is fair. The other has a probability density function such that f(24)=f(28)=0.28, with its remaining sample points equi-probable and not equal f(24) Denote the rolling of the fair die as the random variable X. Denote the rolling of the non-fair die as the random variable...
