Six batteries are needed in the production of toy trucks. The quality assurance department requires that each truck be tested before it gets boxed for distribution. During this test, if one of the batteries is dead, the toy truck will not function and would have to be reworked and be sent back. Assume that the batteries are obtained from a large lot that consists of 20% dead batteries. Calculate the probability that a toy would have to be reworked. What is the probability that out of five toy trucks, two will not function?
