P(black socks): 24/42 or 12/21
P(black socks without replacing): 23/41. As a result, the probability of randomly picking 2 black socks, without replacement, from the basket is 12/21×23/41=276/861 or 32%. Hope it help!
Answer:
Step-by-step explanation:
The given trigonometric equation is
for 
.
We divide through by 5 to get;
We take the inverse tangent of both sides to obtain;
Since the tangent ratio is positive, it means 
could also be in the 3rd quadrant. But this is outside the given range.
Therefore the correct answer is A
