A machine has fourteen identical components that function independently.It will stop working if three or more components fail.If the probability that component fails is equal to 0.1,find the probability that the machine will be working.

It is possible for a computer to pick up an erroneous signal that does not show up as an error on the screen.The error is called a silent error.A Particular terminal is defective and when while using the system 'word processor' it introduces a silent paging error with probability 0.1.The word processor is used 20 times during a given week.(1)Find the probability that no silent paging errors occur.
