Hello all -
Just completed a practice session using the GmatPrep software and since ETS doesn't provide solutions, I am hoping someone can help solve/explain the steps to getting the solution. Please help! Here goes:
In a survey of 248 people, 156 are married, 70 are self employed, and 25 percent of those who are married are self employed. If a person is to be randomly selected from those surveyed, what is the probability that the person selected will be self employed but not married?
a) 1/8 b) 4/31 c) 117/248 d) 1/4 e) 31/117
