A box contains different-colored marbles. If P(blue) = , P(green) = , and P(blue and green) = , which statement is true?

The events are independent because P(blue) P(green) = P(blue and green).
The events are independent because P(blue) P(green) P(blue and green).
The events are dependent because P(blue) P(green) = P(blue and green).
The events are dependent because P(blue) P(green) P(blue and green).

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
