In a survey 199 people were asked if the amount of fresh water should be reduced (yes or no) and if they fish in the salt water (yes or no).

What is the probability that a person who goes fishing in the salt water believes the amount of fresh water should NOT be reduced?

•  $\frac{98}{110}$ 

•  $\frac{12}{110}$ 
  

• $\frac{98}{199}$
  

• $\frac{12}{199}$
