Answer:
0.27
Step-by-step explanation:
Suppose A is the event of defect in the brake system and B is the event of defect in the fuel system,
We have given,
P(A) = 0.25,
P(B) = 0.17
P(A∩B) = 0.15 ( the probability of defects in both systems simultaneously is 0.15 ),
We know that,
P(A∪B) = P(A) + P(B) - P(A∩B)
= 0.25 + 0.17 - 0.15
= 0.27
Hence, the probability that the defect is the brakes or the fueling system is 0.27.
