Answer: 9 / 70

Explanation:


Find attached the image with the grid that accompanies this question.


1) The grid has area 7 × 10 units²

⇒ area = 70 units²

2) The figure inside the grid is a triangle with base 6 units and height 3 units.

⇒ area of the triangle = base × height / 2 = 6 units × 3 units / 2 = 9 units²

3) Probability = area of the triangle / area of the grid

⇒ Probability = 9 units² / 70 units² = 9 /70
