Question 285300
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 ONLY = 18% + 8% = {{{highlight_green(26)}}}%.
