your 3 percentages that are given are-
30% (running)
20% (biking)
12% (both)
and they asked you what percents does one or the other, so you would add together 30% and 20% and get 50%

Since 30% of the executives run, 20% of them bike, and 12% do both, then the percent of executives who only run is 18% (30% - 12%), and the percent of executives who only bike is 8% (20% - 12%).

Therefore, the percent of executives who either run or bike = percent of those who RUN ONLY, plus the percent of those who BIKE DISABLED_event_ONLY= 18% + 8% = %.
