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 flight, the probability of a radio failure is 0.0052. What is the probability that a particular flight will be threatened with the failure of both radios?   Round to 6 decimal places as needed
