$|\Omega|=\binom{5}{2}=\dfrac{5!}{2!3!}=\dfrac{4\cdot5}{2}=10\\
|A|=1\\\\
P(A)=\dfrac{1}{10}=10\%$

Answer:

The answer is 2x + y - 3z

Step-by-step explanation:

∵ $log_{2}P=x$

∵ $log_{2}Q=y$

∵ $log_{2}R=z$

∵ $log_{2}\frac{P^{2}Q}{R^{3}} =$

$log_{2}P^{2}+log_{2}Q-log_{2}R^{3} =$

$2log_{2}P+log_{2}Q-3log_{2}R$

∴ 2x + y - 3z

BlackZzzverrR [31]

We develop two different right triangles in which the opposite side to the given angle of depression is 1500 ft and the length of the runway is the y.
(45°) --> tan (45°) = 1500 ft / y₁
y₁ = 1500 ft
(42⁰) --> tan (42⁰) = 1500 ft / y₂
y₂ = 1665.92 ft
Finding the difference between two y's, the answer would be 165.92 ft.
