A jar contains 6 red marbles numbered 1 to 6 and 12 blue marbles numbered 1 to 12. A marble is drawn at random from the jar. Find the probability of the given event. (a) The marble is red
Your answer is :

(b) The marble is odd-numbered
Your answer is :

(c) The marble is red or odd-numbered
Your answer is :

(d) The marble is blue and even-numbered
Your answer is :

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
