If two lines l and m have equations y = -x + 6, and y = -2x + 6, what is the probability that a point randomly selected in the 1st quadrant and below l will fall between l and m? Express your answer as a decimal to the nearest hundredth.

Line "l" forms a triangle with a base of 6 and a height of 6.....its area = (6 *6) / 2 = 18
The area between these lines forms a triangle with a base of 3 and a height of 6....its area = (3 * 6) /2 = 9
The probability that a selected point falls between the lines = 9/ 18 = 1/2 = .50
