Data on college graduates' employment indicate that 30% of the graduates find a part-time job within a year
of their graduation, 30% of them find a full-time job and the rest of them are unemployed.
If we randomly select 3 graduate students within a year of their graduation, what is the probability
that at least one of them has a job (full-time or part-time)?
~~~~~~~~~~~~~~~~~~~~~ 


The probability that no one of the three graduate students has full-time or part-time job is  %281-0.3-0.3%29%5E3 = 0.4%5E3 = 0.064.


The probability that at least one of the three graduate students has full-time or part-time job is  the COMPLEMENT to it 


                P = 1 - 0.064 = 0.936 = 93.6%.      ANSWER

Solved.
