Step-by-step Answer:
The coordinates of the mid-point of a segment whose end-points are known is the average of the coordinates of the end-points.
Here, the end-points are: (-11,0), (9,-1)
So the x-coordinate of the mid-point is (-11+9)/2 = (-2/2) = -1, and
the y-coordinate of the mid-point is (0-1)/2 = -0.5
So the mid-point is (-1,-0.5)

Answer:
18/95
Step-by-step explanation:
At first, there are 20 cubes, 9 of which are black. The probability that the first cube is black is P = 9/20.
After the first cube is selected, there are 19 cubes left, 8 of which are black. The probability that the second cube is black is P = 8/19.
The total probability is:
P = (9/20) (8/19)
P = 18/95
