A region's govemment requires that commencial aircrat used for tying in hazardous ndependent radios instead of one.

Explanation / Answer

Probability of one radio failure = 0.0042

Hence,

Probability of both radios failing = 0.0042 * 0.0042 = 0.000018

B option, safety increases with second radio as serious problem probability reduces.
