In a group of 140 adults, 92 watch tennis, 81 play a sport and 40 do neither. Find the probability that an adult chosen at random from those who watch tennis does not play a sport

PROBABILITY =11/140 or 8% (approx.)

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.

The correct graph is the second one, with the points being at (-6,0), (2,0) and reaching down to (-2,-8)
