The table below shows the gender in amount of time each person surveyed exercises each day. What is P(do not exercise male)?

slava [35]

Total people = male + female = 82+18+94 +46= 240

People that do not exercise and is male: 18

To find the probability divide the number of people that do not exercise and are male, by the total number of people.

18/240 = 0.075

P = 0.075

$x-the\ first\ number\\6x-the\ second\ number\\6x+5-the\ third\ number\\\\(x)+(6x)+(6x+5)=61\\x+6x+6x+5=61\\13x+5=61\ \ \ \ |subtract\ 5\ from\ both\ sides\\13x=56\ \ \ \ |divide\ both\ sides\ by\ 13\\\boxed{x=\frac{56}{13}\to x=4\frac{4}{13}-the\ first\ number}\\\boxed{6x=6\cdot\frac{56}{13}=\frac{336}{13}=25\frac{11}{13}-the\ second\ number}\\\boxed{6x+5=25\frac{11}{13}+5=30\frac{11}{13}-the\ third\ number}$
