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?
+36916 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 %
