Question

There is park of length 500 m and width 400m . the park contains a parking area of lengtj 50m and breadth 30m in one of its corner. Find the probability that a car is inside the park but not parked in the parking area .

Answer 1

Area of park = length of park × width of park
= 500 m × 400 m
= 200000 m²

Area of car parking = length × width
= 50 m × 30 m
= 1500 m²

Area of rest park = area of park - area of car parking
= 200000 - 1500
= 198500 m²

Now, probability = area of rest part of park/area of park
= 198500/200000
= 1985/2000
= 0.9925
