A survey of athletes at a high school is conducted, and the following facts are discovered: 29% of the athletes are football players, 63% are basketball players, and 24% of the athletes play both football and basketball. An athlete is chosen at random from the high school: what is the probability that he is either a football player or a basketball player?

Out of 100      29 play football     63 play basketball   24 play both     8 play another sport

                        

subtract 24      5  play football ONLY  49 play basketball only

 

so  out of 100   there is a  5  + 49 + 24   chance they play either        78/100 = 78 %
