Question

The principle of redundancy is used when system reliability is improved through redundant or backup components. A region's government requires that commercial aircraft used for flying in hazardous conditions must have two independent radios instead of one. Assume that for a typical fight, the probability of a radio failure is 0.0034. What is the probability that a particular fight will be threatened with the failure of both radios? Describe how the second independent radio increases safety n this case. What is the probability that a particular flight will be threatened with the failure of both radios? Round to six decimal places as needed.)

Explanation / Answer

1)probabilty that both radio failed=0.0034*0.0034=0.000012

2)probabilty =(14/142)*(13/141)=0.009
