In triangle T with vertices at (0,0), (6,0), and (0,6), what is the probability that a point selected within this triangle has a y-coordinate less than twice its x-coordinate?

In triangle T with vertices at (0,0), (6,0), and (0,6), what is the probability that a point selected within this triangle has a y-coordinate less than twice its x-coordinate?

• A. 1/3
• B. 2/3
• C. 1/2
• D. 1/4

Answer: (B)

To determine the probability that a point selected within triangle T has a y-coordinate less than twice its x-coordinate, we first need to analyze the area of triangle T and the region where the condition \( y < 2x \) holds. The vertices of triangle T are at (0,0), (6,0), and (0,6). The triangle is right-angled and lies in the first quadrant with a base and height of 6 units each. The area of the triangle can be calculated using the formula for the area of a triangle: \[ \text{Area} = \frac{1}{2} \times \text{base} \times \text{height} = \frac{1}{2} \times 6 \times 6 = 18. \] Next, we need to find the area within this triangle where the condition \( y < 2x \) is satisfied. The line \( y = 2x \) intersects the triangle at some point. To find that intersection, we can set up inequalities based on the limits of the triangle: 1. The line \( y = 2x \) intersects the side of the triangle along the x-axis (where \( y =
