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.

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24

answer: can you give the

step-by-step explanation:

hello, sorry being so rude after all that fighting i found it kind of funny, so as me saying sorry here is an answer!

since the table showed her that   2km = 2000m.

to determine, how many km in 2000m, she would divide by 1000.

= 2000 / 1000 = 2 km.

similarly, for 8000m = 8000 / 1000 = 8 km

cheers to savings
