I think the answer is 1/2. C.
Since you mentioned the fundamental counting principle, I assume you are looking for the total number of possibilities.
If you are picking a month, there are 12 options.
If you are selecting a day of the week, there are 7 options.
If you are doing both, you multiply the two numbers together.
12 x 7 = 84
8x-9y=11
Add 9y to both sides
8x = 11 + 9y
Subtract 11 on both sides
8x - 11 = 9y
Divide 9 on both sides
Answer:

Step-by-step explanation:
Given that alpha and beta be conjugate complex numbers
such that frac{\alpha}{\beta^2} is a real number and alpha - \beta| = 2 \sqrt{3}.
Let

since they are conjugates


Imaginary part of the above =0
i.e. 
So the value of alpha =
