Question:
In a survey of 200 ladies, it was found that 82 like coffee while 118 dislike it. From these ladies, one is chosen at random. What is the probability that the chosen lady dislikes coffee?
Solution:
Total number of ladies surveyed $=200$
Number of ladies who dislike coffee $=118$
If chosen randomly, $P_{(a \text { lady that dislikes coffee })}=\frac{118}{200}=\frac{59}{100}$
