Two dice are rolled. use the complement rule to find that the sum of the dice is less than 10

17/20

there are 20 different sums but 3 of them add up to 10 and more such as 6+4=10, 5+5=10, 6+5=11

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)

hello! just here for points! though i wish i knew!
