Survey of 125 members of a local gym is conducted and the results displayed below show that, of the two flavors of a particular brand of vitamin water available, 39 members prefer passion fruit, 71 members prefer tropical grape, and 92 members would buy one or the other or both. Fill in the remainder of the two-way frequency table. Passion FruitNot Passion FruitTotal
Tropical Grape 71

What is the probability (rounded to the nearest whole percent) that a randomly selected gym member would buy passion fruit vitamin water but not tropical grape vitamin water?

(15ab/4)*[8/(9a^2b^2]=5*3ab/2^2*[2^3/(3^2a^2b^2)]
(15ab/4)*[8/(9a^2b^2]=5*3*2^3ab/(2^2*3^2a^2b^2)
(15ab/4)*[8/(9a^2b^2]=5*2^(3-2)/[(3^(2-1)a^(2-1)b^(2-1)]
(15ab/4)*[8/(9a^2b^2]=5*2^1/(3^1a^1b^1)
(15ab/4)*[8/(9a^2b^2]=5*2/(3ab)
(15ab/4)*[8/(9a^2b^2]=10/(3ab)
