a merriory rriodule consists of nine chips. the device is designed vvit h redundancy so tliat it \vorks even if one of its chips is defective. eacli chip contains n, transistors and functions properly only if all of its transistors v\rork. a trarisistor v\rorks \vitli probabilit}' '[j independent of an}' other transistor. (a) what is the probability p (c) that a cliip v\rorks? (b) vvliat is tlie probability p(jij) that the rriernory rriodt1le \vorks?
