1.	A missing helicopter is reported to have crashed somewhere in the rectangular region shown in Fig. 15.2. What is the probability that it crashed inside the lake shown in the figure?
Answer» The helicopter is equally likely to crash anywhere in the region. Area of the entire region where the helicopter can crash = (4.5 × 9) km² = 40.5 km² Area of the lake = (2.5 × 3) km² = 7.5 km² Therefore, P (helicopter crashed in the lake) =7.5/40.5=75/405=5/27

Answer»

The helicopter is equally likely to crash anywhere in the region.

Area of the entire region where the helicopter can crash

= (4.5 × 9) km² = 40.5 km²

Area of the lake = (2.5 × 3) km² = 7.5 km²

Therefore, P (helicopter crashed in the lake) =7.5/40.5=75/405=5/27
