Let the joint pmf of x and y be defined by f(x, y)= x+y 32 , x=1,2, y=1,2,3,4. (a) find fx(x), the marginal pmf of x. (b) find fy(y), the marginal pmf of y. (c) find p(x > y). (d) find p(y =2x). (e) find p(x+y =3). (f) find p(x ≤3−y). (g) arex andy independentordependent? whyorwhy not? (h) find the means and the variances of x and y.

so what is the question

step-by-step explanation:

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it

x = 3 ± √(5+y)

lol, i have been using this product for a while and the second half of the year for a lon and the first time in a long time ago that the government has not yet received enough votes to be a good the first place in the world to be able to do it in my world life, i
