Show that reflexive sentences are independent from symmetric, and transitive sentences by constructing a structure that satisfy symmetric and transitive quality but not reflexive.

Reflexive :∀xE(x, x)
symmetric :∀xy(E(x, y) → E(y, x))

transitive: ∀xyz(E(x, y) ∧ E(y, z) → E(x, z))

X, Y, Z are 3 independent random variables. We know that Y, Z is the 0-1 random variables indicating whether tossing a regular coin gets a head (1 means getting a head and 0 means not). We also know the following equations, E(X2Y +XYZ)=7 E(XY 2 + XZ2) = 3 Please calculate the expectation and variance of variable X.
Suppose that X, Y, and Z are independent, with E[X]=E[Y]=E[Z]=2, and E[X2]=E[Y2]=E[Z2]=5. Find cov(XY,XZ). (Enter a...
Suppose that X, Y, and Z are independent, with E[X]=E[Y]=E[Z]=2, and E[X2]=E[Y2]=E[Z2]=5. Find cov(XY,XZ). (Enter a numerical answer.) cov(XY,XZ)= Let X be a standard normal random variable. Another random variable is determined as follows. We flip a fair coin (independent from X). In case of Heads, we let Y=X. In case of Tails, we let Y=−X. Is Y normal? Justify your answer. yes no not enough information to determine Compute Cov(X,Y). Cov(X,Y)= Are X and Y independent? yes no not...

1. Suppose we have the following relation defined on Z. We say that a ∼ b iff 2 divides a + b. (a) Prove that the relation ∼ defines an equivalence relation on Z. (b) Describe the equivalence classes under ∼ . 2. Suppose we have the following relation defined on Z. We say that a ' b iff 3 divides a + b. It is simple to show that that the relation ' is symmetric, so we will leave...
