What is the probability that a student selected at random in the university is a male in the business faculty? b. What is the probability that a student selected at random in the university is male or is in the business faculty? c. What percentage of males are in the business faculty?

Correct answer:

a =  16.5 %
b =  74.5 %
c =  66 %

Step-by-step explanation:

a=100 10025 10066=233%=16.5%
f=166/100=5017=0.34 b=125/100=2149=74.5  n=f b=5017 2149=50 217 149=1002533=20051=0.255 b=100 (1n)=100 (120051)=74.5%
c=66=66%

Question C) seems a bit misleading as one might think that it requires the percentage that male business students make up of the whole male population of students at the university.
