Quizplus · Accepted Answer

The reliability of Component 1 is given by R1 = 0.95, Component 2 has R2 = 0.94, and Component 3 has R3 = 0.93. Since both components have to function for the product to function, the overall reliability of the product is given by R = R1 × R2 × R3 = 0.95 × 0.94 × 0.93 = 0.884. Therefore, the best choice is D.
