Answer:
5/27
Step-by-step explanation:
Area of rectangle = l × b = 9 × 4.5
Area of Rectangle = 40.5 km^2
Length of Lake = (9 - 6) km = 3 km
Breadth of Lake = (4.5 - 2) = 2.5 km
Area of lake = l × b = 3 × 2.5
Area of lake = 7.5 km^2
Probability of crashing in lake = (7.5/40.5)
Probability of plane crashing in lake is 5/27
