Failures are due to electrical components


Test results on a type of circuit board indicate that 20% of failures are caused by assembly defects, 70% are due to electrical components, and 10% are due to mechanical defects. Suppose 5 boards have failed independently. What is the probability that all of the failures are due to electrical components?
