You can
put this solution on YOUR website!A survey of 100 MBA students found that 60 owned mutual funds, 40 owned stocks, and 20 owned both.
a. What is the probability that a student owns a stock? A mutual fund?
probability
mutual 60 0.6
stocks 40 0.4
b. What is the probability that a student owns neither stocks nor mutual funds?
i. P(neither) = 0
c. What is the probability that a student owns either a stock or a mutual fund?
i. P(s or mf) = P(s) + P(mf) - P(s and mf)
= (0.4) + 0.6 - 0.2
= 0.80
