Answer:
P(working product) = .99*.99*.96*.96 = .0.903
Step-by-step explanation:
For the product to work, all four probabilities must come to pass, so that
P(Part-1)*P(Part-2)*P(Part-3)*P(Part-4) 
where 
P(Part-1) = 0.96
P(Part-2) = 0.96
P(Part-3) = 0.99
P(Part-4) = 0.99
As all parts are independent, so the formula is P(A∩B) = P(A)*P(B)
P (Working Product) =  P(Part-1)*P(Part-2)*P(Part-3)*P(Part-4) 
P (Working Product) = 0.96*0.96*0.96*0.99*0.99
P(Working Product) = 0.903
