In rolling two dice, what is the probability that the sum of the two numbers on the dice will be 4? A: 1 over 12
B: 3
C: 11 over 12
D: 2 over 3

A, b, c, and d have the coordinates (-8, 1), (-2, 4), (-3, -1), and (-6, 5), respectively. which sentence about the points is true? a. a, b, c, and d lie on the same line. b. and are perpendicular lines. c. and are parallel lines. d. and are intersecting lines but are not perpendicular. e. and are parallel lines.

Math i have no idea how to do a and b

Suppose the equation ||x-a|-b|=2008 has 3 distinct real roots and a not =0. find the value of b.
