Best answer
The correct answer is (c) 0.354

To explain I would say: We can see that total number of events of being elder than 35 years of age and having at least 1 accident = 277 + 78 + 118 + 59

= 532

Total number of events = 1500

Hence, probability of being 18-29 years of age and having more than 1 accidents = \(\frac{532}{1500}\)

= 0.354.
