13 An electronic system has three components X, Y, and Z connected in series. The reliabilities of X and Y are 0.80 and 0.72 respectively. If the reliability of the whole system is 0.30 then what must be the reliability of the component Z? [Select the appropriate range in which your answer falls.] More than O but less than or equal to 0.20 More than 0.20 but less than or equal to 0.40 More than 0.40 but less than or equal to 0.60 More than 0.60 but less than or equal to 0.80 More than 0.80
