    `There are 40 people who liked hatchbacks` this goes in the "liked hatchbacks" row and "total" column. Basically saying "the total of people who liked hatchbacks is 40"

    Ok so can we just review that.... A=15 B= 25 When we add those two we get C=40 D=10 E=??? What did we say E was? is it 50? when we add 50+10 we get F=100 G=25 H=i guess 75, if e is 50 25+75 is I=100

    G+H = 100 25+H = 100 solve for H to get H = 75

    or you can solve for F in C+F = 100 40+F = 100 either way, F = 60

    So the number would be 50, right? And then we divide that by 100. so 0.50 or 50% is that right?

    number who don't like sedans OR hatchbacks = (number who don't like sedans) + (number who don't like hatchbacks) - (number who don't like both)

    the subtle difference is that 50% would be if it said "what percentage didn't like BOTH types" or "what percentage didn't like sedans AND hatcbacks". They didn't just hate 1 car. They hate both cars.
