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.
If you really want to figure this out you make an equation to solve for the time
let's let
x = time from Elena to Jada and
x = time from Jada to Elena
12 then the equation
12 = 5x +3x
would help figuring out their distance say for one of them
12 = x(5+3)
12/8 = x
1.5 = x
1. 5 hours they will meet up
