Given : At a parking, there are 100 vehicles, 60 of which are cars, 30 are busses and the remainder lorries. every vehicle is equally likely to leave,
To Find : the probability of car leaving second if either a lorry or van had left first:
Solution:
Total vehicles = 100
Cars = 60
Buses = 30
Trucks = 100 - 60 - 30 = 10
Not cars = 100 - 60 = 40
car leaving second = car leaving not 1st x car leaving 2nd
= (40/100) * (60/99)
= 24/99
=8/33
= 0.2424
0.2424 = 8/33 is the probability of car leaving second if either a lorry or van had left first:
