Question

A farmhouse has a parking space of 20 cars.5 cars with number plate 'DL', 6 cars with number plate 'HR'and 4cars with number plate 'UP' are parked inside. Find the probability that the first car to exit the farmhouse is having the number plate starting with 'HR'.

Answer 1

probability (getting the first car to exit the farmhouse is having the number plate starting with 'HR')= 6/15

Answer 2

Number of cars with number plate DL = 5
Number of cars with number plate HR = 6
Number of cars with number plate UP = 4
Total number of cars parked inside = 15
Total number of possible outcomes = 15
Number of cars with number plate HR = 6
Number of favourable outcomes = 6
6
Required probability= number of favourable outcome/Total number of outcomes = 6/15 = 2/5
