We find the probability of intersection using the inclusion/exclusion principle:

By definition of conditional probability,

For

and

to be independent, we must have

in which case we have

, which is true, so

and

are indeed independent.
Or, to establish independence another way, in terms of conditional probability, we must have

which is also true.
'Parallel' means parallel TO something else. A single line all by itself
is not "a parallel line", until we know the other line that it's parallel TO.
There are an infinite number of lines that pass through (0, -2).
Give us another line, and we'll find the one that's parallel to it.
The lcm of 6 and 7 is 42.
Answer:
ΔABC≅ΔDEF by AAS (Angle-Angle-Side) Theorem
Step-by-step explanation:
We observe that
,
for the included angle, and
for our side. Thus, the AAS Theorem proves that the triangles are congruent to each other
