Reliability testing
The components $C_1, C_2, C_3, C_4, C_5, C_6$ are linked as in the following diagram.
Find the reliability $R$ of the system if $C_1, C_2, C_3, C_4, C_5, C_6$ have reliabilities $R_1, R_2, R_3, R_4, R_5, R_6$ with values $R_1 = 0.97, R_2 = 0.87, R_3 = 0.82, R_4 = 0.82, R_5 = 0.82, R_6 = 0.82$.
Give your answer with full accuracy, i.e. do not round your answer.
$R = $
