Good weather Bad Weather Delayed 7.5% 17.5% On Time 42.5% 32.5% Given these percentages, during bad weather, is it more likely that your flight will be delayed or on time? How much more likely? It is 30% more likely to be delayed. It is 15% more likely to be delayed. It is 30% more likely to be on time. It is 15% more likely to be on time.

Answer 1

The answer would be: It is 15% more likely to be delayed.

The table should look like this:
              Good weather Bad Weather
Delayed 7.5%                17.5%
On Time 42.5%             32.5% 

The question is asking whether the probability when "bad weather" and "on time" more likely than "On time". So, you need to find the difference between them. The calculation would be:32.5%- 17.5%= 15%

Answer 2
