A fly lands at random at a point on the grid. Find the probability of the fly landing on the figure
1 answer:
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
