An electronic assembly consists of two subsystems $A$ and $B$. Past testing procedures data show that probabilities of failure are $P(A$ fails $)=0.2, P(B$ fails alone $)=0.15$, $P(A \& B$ fail $)=0.15$. Then the probability that $A$ fails alone is equal to
  1. $0.02$
  2. $0.03$
  3. $0.04$
  4. $0.05$
