A pumping station in a mine has 4 pumps, P₁, P₂, P₃ and P₄ which are connected functionally in parallel configuration as shown in the figure. The individual reliability of the pumps P₁, P₂, P₃ and P₄ are 0.80, 0.90, 0.85 and 0.95 respectively. For an effective dewatering operation in the mine denoting system success, at least three pumps should be in operation. The reliability of the system is
