kari74 [83]

Let the angle of elevation be θ.

We have a right angled triangle with an opposite of 300.5 ft. (306 - 5.5) and an adjacent of 400 ft. Recalling SOH CAH TOA, tanθ = O/A.
tan(θ) = 300.5/400.
θ = tan^-1(300.5/400).
θ = 36.9°.

A distribution is given as

Arada [10]

If X is uniformly distributed on the interval (0, 12), then its PDF is

$f_X(x) = \begin{cases}\frac1{12} & \text{if }0 < x < 12 \\ 0&\text{otherwise}\end{cases}$

or simply

$f_X(x) = \dfrac1{12} \text{ where } 0 < x < 12$

and the zero-elsewhere case is assumed.

Whether you include 0 and 12 in the domain is irrelevant, since the probability that X = 0 or X = 12 are both zero.
