ohhh no typon hope it helps
Both point (5,12) and (11,12) lie on the horizontal line y=12.
If these two points is a leg of the triangle, the other leg must be perpendicular to the horizontal line, that is, the other leg must be vertical, but passing through either (5,12) or (11,12), i.e. lies on either the vertical line x=5 or x=11.
There is only one point that passes through x=11, i.e. point A(11,4).
The formula for the conditional probability is:

This indicates the probability of event A, given that event B has already occurred.
Here P(A*B) indicates P(A∩B).
Using the given values, in the formula, we can write:
Therefore, option D is the correct answer.
