What does p(x y) mean-{(x,y) x y ≥ 1}, which is the region above the line y = 1 − x See figure above, right To compute the probability, we double integrate the joint density over this subset of the support set P(X Y ≥ 1) = Z 1 0 Z 2 1−x (x2 xy 3)dydx = 65 72 (c) We compute the marginal pdfs fX(x) = Z ∞ −∞ f(x,y)dy = ˆR 2 0 (x 2 xy 3)dy = 2x2 2x 3 if 0 ≤ x ≤ 1P(Y) is listed in the World's largest and most authoritative dictionary database of abbreviations and acronyms P(Y) What does P(Y) stand for?

Z = (X – mean)/stddev, where X is the random variable Question is to find cumulative value of P(XP X (x) = { 05 for x = − 100 05 for x = 100 0 otherwise (33) P Y (y) = { 1 for y = 0 0 otherwise (34) Note that E X = E Y = 0 Although both random variables have the same mean value, their distribution is completely differentTrue, then automatically the statement ∀x ∈ A,∃y ∈ B,P(x,y) must be true (but in general it doesn't go the other way) Aside Occasionally, you will see a nested quantifier at the end of a statement, in which case it is implied that the quantifier is the last in terms of order For example, here is the definition of bounded

Heads obtained by B Find P(X > Y) • Discrete case Joint probability mass function p(x,y) = P(X = x,Y = y) – Two coins, one fair, the other twoheaded A randomly chooses one and B takes the other X = ˆ 1 A gets head 0 A gets tail Y = ˆ 1 B gets head 0 B gets tail Find P(X ≥ Y) 1The next function we look at is qnorm which is the inverse of pnorm The idea behind qnorm is that you give it a probability, and it returns the number whose cumulative distribution matches the probability For example, if you have a normally distributed random variable with mean zero and standard deviation one, then if you give the function a probability it returns the associated ZscoreXy distance distance between points x and y xy = 5 π pi constant π = is the ratio between the circumference and diameter of a circle c = π⋅d = 2⋅π⋅r rad radians radians angle unit 360° = 2π rad c radians radians angle unit 360° = 2π c grad gradians / gons grads angle unit 360° = 400 grad g gradians / gons grads angle unit 360° = 400 g

In fact we can think of it as being the population mean (as opposed to the sample mean) The variance is the expectation of (X −EX)2 Var(X) = X x p(x)(x−EX)2 1P(A) probability function probability of event A P(A) = 05 P(A ∩ B) probability of events intersection probability that of events A and B P(A (X,Y) = 06 ρ X, Y correlationP x Pr(X = x,Y = y) = Pr(X = x), likewise P x Pr(X = x,Y = y) = Pr(Y = y) So, EX Y = X x xPr(X = x) X y yPr(Y = y) = EXEY Notice that EX works just like a mean;

The distance of a point from the yaxis on a graph in the Cartesian coordinate system It is measured parallel to the xaxis For example, a point having coordinates (2,3) has 2 as its abscissaLet's say you have an equation in x and y Now you are to solve it and find y, but u don't have enough information about the other variable ie x, and it's said that u can leave it in terms of x Which means , u will have something like y = x andIn fact we can think of it as being the population mean (as opposed to the sample mean) The variance is the expectation of (X −EX)2 Var(X) = X x p(x)(x−EX)2 1
