There is a Tata motors car manufacturing unit in Gujrat. Out of all the manufactured cars, some come out to be having a defect in engine. These cars are loaded in containers to be transported. Three cars are selected at random from the container by the testing team. If at least 2 out of 3 cars are tested OK, then only the container is transported; otherwise it is put on hold. The probability of container getting transported is:
1
1/3
