Using the rule of thumb discussed in class, without performing any calculations, identify a maximum value for the overall reliability of a seven step process $($all steps in the process are mutually independent$)$ with the following individual reliabilities. The reliability of step $1$ in the process is $0\mathrm{.}95.$ The reliability of step $2$ in the process is $0\mathrm{.}92.$ The reliability of step $3$ in the process is $0\mathrm{.}87.$ The reliability of step $4$ in the process: $0\mathrm{.}65.$ The reliability of step $5$ in the process is $0\mathrm{.}7.$ The reliability of step $6$ in the process is $0\mathrm{.}77$ and the reliability of step $7$ in the process is $0\mathrm{.}81.$ What is the maximum overall reliability of this process?
