0.66

Step-by-step explanation:

Given that a  survey of athletes at a high school is conducted, and the following facts are discovered: 24% of the athletes are football players, 55% are basketball players, and 13% of the athletes play both football and basketball.

= $24%+55%-13%\\=66%$

i.e. Probability reqd  =0.66
