Detailed Solution

In a survey, it was found that 36 ladies like coffee while 64 dislike it. Out of these 100 ladies, one is chosen at random. Then the probability that the chosen lady likes coffee is

Given data,
The total number of ladies in a survey = 100.
The number of ladies likes coffee = 36.
Applying the formula of probability,
Probability of choosing a lady who likes coffee =

\frac{Number of ladies who likes coffee}{Total number of ladies}

P(E) =

\frac{36}{100}

= \frac{9}{25}

Therefore, the correct answer is
