A large but sparsely populated county has two small hospitals, one at the south end of the county and the other at the north end

mojhsa [17]

Answer:

Follows are the solution to this question:

Step-by-step explanation:

In point a:

Although both variables are non - stationary, for both the respective pmf, multiply all pmf principles. For example:

$\to P(x=0,y=0)=P(x=0)\times P(y=0)$

$X$

$0 \ \ \ \ \ \ \ \ \ \ \ \ \ \ 1\ \ \ \ \ \ \ \ \ \ \ \ \ \ 2\ \ \ \ \ \ \ \ \ \ \ \ \ \ 3 \ \ \ \ \ \ \ \ \ \ \ \ \ \ 4 \ \ \ \ \ \ \ \ \ \ \ \ \ \ pmf Y$

$0 \ \ \ \ \ \ \ \ \ \ \ \ \ \ 0.01 \ \ \ \ \ \ \ \ \ \ \ \ \ \ 0.02 \ \ \ \ \ \ \ \ \ \ \ \ \ \ 0.03\ \ \ \ \ \ \ \ \ \ \ \ \ \ 0.02\ \ \ \ \ \ \ \ \ \ \ \ \ \ 0.02\ \ \ \ \ \ \ \ \ \ \ \ \ \ 0.1$

$Y \ \ \ \ \ \ \ \ \ \ \ 1 \ \ \ \ \ \ \ \ \ \ \ 0.03 \ \ \ \ \ \ \ \ \ \ \ 0.06 \ \ \ \ \ \ \ \ \ \ \ 0.09 \ \ \ \ \ \ \ \ \ \ \ 0.06 \ \ \ \ \ \ \ \ \ \ \ 0.06 \ \ \ \ \ \ \ \ \ \ \ 0.3$

$2 \ \ \ \ \ \ \ \ \ 0.04\ \ \ \ \ \ \ \ \ 0.08\ \ \ \ \ \ \ \ \ 0.12 0.08\ \ \ \ \ \ \ \ \ 0.08\ \ \ \ \ \ \ \ \ 0.4\\\\ 3\ \ \ \ \ \ \ \ \ 0.02\ \ \ \ \ \ \ \ \ 0.04\ \ \ \ \ \ \ \ \ 0.06\ \ \ \ \ \ \ \ \ 0.04\ \ \ \ \ \ \ \ \ 0.04\ \ \ \ \ \ \ \ \ 0.2\\\\pmf X \ \ \ \ \ \ \ \ \ 0.1\ \ \ \ \ \ \ \ \ 0.2\ \ \ \ \ \ \ \ \ 0.3\ \ \ \ \ \ \ \ \ 0.2\ \ \ \ \ \ \ \ \ 0.2$ `

In point b:

$\to P(x$

In point c: $\to P(X+Y$

In point d:

$\to P(X=0,Y=1)+P(X=0,Y=2)+P(X=0,Y=3)+P(X=0,Y=0)+P(X=1,Y=0)+P(X=2,Y=0)+P(X=3,Y=0)+P(X=4,Y=0) \\\\ \to 0.03+0.04+0.02+0.01+0.02+0.03+0.02+0.02=0.19$

The three incoming currents at a node in an electrical circuit measure 0.7 amps, 0.68 amps, and 0.47 amps two of the three outgo

OLga [1]

What goes in goes out. This means none of the current is lost. So if 0.7amps+0.68amps+0.47amps = 1.85 amps comes in, then 1.85 amps goes out. So far we have 0.8 amps+0.55 amps going out= 1.35 amps. This means we need an additional 1.85-1.35amps going out= 0.5 amps for the third outgoing current. Cheers!
