Answer:

Step-by-step explanation:
The location of a point O(x, y) which divides line segment AB in the ratio a:b with point A at (
) and B(
) is given by the formula:

From the graph, the location of the point is P(2, 5), R(1, -7). Let point Q be (x, y) which divides PR in ratio 2:1. Coordinates of point Q is at:

Point Q is at 
Answer:
ok so
7+3+3+1=14
and if you pull one out the chance is
3/14
then
2/13
so 3/14*2/13
0.03296703296
so the answer is
0.03
