The probability that a customer is currently an undergraduate, calculated using the addition rule for mutually exclusive events, is 0.35. The probability of not being an undergraduate in business is 0.80, found using the complement rule.

Given:

20% are currently undergraduate students in business (U in Business)

15% are undergraduate students in other fields (U in Other Fields)

60% are college graduates who are currently employed (Grad & Employed)

- ? are college graduates who are not employed (Grad & Not Employed)

(a) Probability that the customer is currently an undergraduate (U):

Using the addition rule for mutually exclusive events:


\[ P(U) = P(U \text{ in Business}) + P(U \text{ in Other Fields}) \]


\[ P(U) = 0.20 + 0.15 \]


\[ P(U) = 0.35 \]

(b) Probability that the customer is not an undergraduate business student:

Using the complement rule:


\[ P(\text{Not U in Business}) = 1 - P(U \text{ in Business}) \]


\[ P(\text{Not U in Business}) = 1 - 0.20 \]


\[ P(\text{Not U in Business}) = 0.80 \]

Therefore:

(a) The probability that the customer is currently an undergraduate is 0.35.

(b) The probability that the customer is not an undergraduate business student is 0.80.
