An electronic circuit contains 500 components. After 1000 h of operation, the probability that a given component has failed is 103. Assume that the failures of various components are independent. If any of the components fail, the cir- cuit will not function. Find the probability that the circuit is functioning after 1000 h. If two similar circuits are available, find the probability that at least one is functional after 1000 h.

Please answer the question and explain fully.
An electronic circuit contains 500 components. After 1000 h of operation, the
probability that a given component has failed is 10-3. Assume that the failures
of various components are independent. If any of the components fail, the cir-
cuit will not function. Find the probability that the circuit is functioning after
1000 h. If two similar circuits are available, find the probability that at least one
is functional after 1000 h.
