If events A and B are
If events A and B are possible (that is P(A) > 0 and P(B) > 0), then the two events cannot be both independent and mutually exclusive.
Awesome summary.. Loving it.

Good question.
We went to find P(length of chord AB is at least 6 inches)
So, if we place point B to the LEFT of point A, then the resulting chord must have a length greater than (or equal to) 6.
Also, if we place point B to the RIGHT of point A, then the resulting chord must have a length greater than (or equal to) 6.
If we don't consider point B on EITHER side of point A, then we are not considering all possible cases (since point B can be placed either to the left or right of point A).
Does that help?
Cheers,
Brent
