Answer : Probability that the pumping system will fail on any given day = 0.005
Explanation:
Probability that only older pump fail = P(A) = 0.10
Probability that only newer pump fail = P(B) = 0.05
Since they are independent events ,
then the conditions will be 
P(A∩B) = P(A). P(B)
              = 0.10 ×0.05
              =  0.005
Hence, the probability will fail on any given day = 0.005
