This is a subjective question, hence, you have to write your answer in the Text$-$Field given below.Solve the following rellability problemsa$)$ A given component has an MTBF of $105$ hr$,$ what is the reliability for an operating period of $10$ hr for $6$ such components in series?b$)$ Four capacitances of $25$F each are connected in parallel to act as a single capacitance of $100$F required for the successful operation of a unit. If the reliabilities of these capacitors are $0\mathrm{.}6,0\mathrm{.}7,0\mathrm{.}8,$ and $0\mathrm{.}9$ respectively, find the reliability of the unit
