The nakagin capsule tower has 140 modules and is 14 stories high if the modules were divided evenly among the number of stories

Burka [1]

To determine the number of modules that is in each story, we simply divide the number of modules by the number of stories.
= 140 / 14
Simplifying,
= 10 modules / story
Therefore, by even distribution we note that there are 10 modules per story.

There are three highways in the county. the number of daily accidents that occur on these highways are poisson random variables

Romashka-Z-Leto [24]

There is a theorem that we can use to find the expected value of a random variable that is a sum of other random variables as follows.

If $X=X_1 + X_2 + ...+X_k$ , then $E(X)=E(X_1)+E(X_2)+...+E(X_k)$ .

In this case, let X = the number of accidents that will happen on any of those highways today,
$X_1,X_2,X_3$ are the numbers of accidents on each highway, respectively.

Then $X = X_1+X_2+X_3$ .

Since $X_1,X_2,X_3$ are Poisson variates, their expected values are the parameters given, .3, .5 and .7.

So $E(X_1)=.3, E(X_2) = .5, E(X_3) = .7$
Thus, $E(X)=E(X_1)+E(X_2)+E(X_3) = .3 + .5 + .7 = 1.5$

The answer is 1.5.
