Out of 60 members of an Association, 15 are Doctors and 9 are Lawyers. If a member is selected at random from the Association, what is the probability that the member is neither a Doctor Nor a Lawyer
A
\(\frac{3}{5}\)
B
\(\frac{9}{10}\)
C
\(\frac{3}{20}\)
D
\(\frac{1}{4}\)
correct option: a
Member that are neither doctors nor lawyers = 60-(15+9)=36
Probability (Not doctors ad not lawyers) \(=\frac{36}{60}\
=\frac{6}{10}=\frac{3}{5}\)
Probability (Not doctors ad not lawyers) \(=\frac{36}{60}\
=\frac{6}{10}=\frac{3}{5}\)
