Given:
Area of a triangle = (h*b) / 2
Area of smaller triangle = (4cm * 4cm) / 2 = 16cm² / 2 = 8 cm²
Area of larger triangle = (6cm * 10cm) / 2 = 60cm² / 2 = 30 cm²
30cm² - 8cm² = 22cm²
Probability that the point is inside the large triangle but outside the small triangle:
22cm² / 30cm² → 11/15 → 0.73 or 73%
