The probability on landing a 5 on a dice is 1/6 what is the best prediction of the amount of times it should land of a 5 if you roll the dice 18 times.

the solution is 12x-6y

i found two solutions,   n = 2 • ± √3 = ± 3.4641

step-by-step explanation:

a

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
