Hi,

probability of the air conditioner failing before the warranty expires is 0.35,

 the probability of the alternator failing is 0.23, 

and the probability of both failing is 0.13.



P(the air conditioner 'or' the alternator failing before the warranty expires) 

Note: P(A or B) = P(A) + P(B) - P(A and B)

P(A or B) = .35 + .23 -.13 = .45
