Question 151764
Note:
PBC= prefer black coffee
NBC= not to black coffee
Out of 100 coffee drinkers, we can say 36 are PBC, and the remaining 64 are NBC
{{{PBC/NBC=36/64=18/32=9/16}}} --->ratio of PBC to NBC
That shows out of 100 coffee drinkers,for every 9 people who prefer black coffee, there are already 16 people who doesn't like black coffee.
Thank you,
Jojo
