Denote:
Probability of not owning a car: P(A) = 0.35
Probability of being older than 30: P(B) = 0.6
Probability of not owning a car and being older than 30: P(A⋂B) = 0.21
=> Probability of either not owning a car or being older than 30:
P(A⋃B) = P(A) + P(B) - P(A⋂B) = 0.35 + 0.6 - 0.21 = 0.74
=> Option D is correct
Hope this helps!

Step-by-step explanation:
P(>30) + P(no car) - P(both)
0.60 + 0.35 - 0.21
0.74 × 100
