Troye teaches two undergraduate Accounting courses at UST. The class for Income Taxation consists of 6 sophomores and 4 juniors.

As an example of a business sampling technique, Professor Shane randomly selects, from the stack of Income Taxation registration cards, the class card of one student and then replaces the card in the stack. If that student was a sophomore, Shane draws another card from the Income Taxation stack; if not, she randomly draws a card from the Business Taxation group. What is the probability of: Interpret your answers. a. A junior’s name on both draws? b. A junior’s name on the first draw? c. A sophomore’s name on both draws? d. A junior’s name on the second draw, given that a sophomore’s name was drawn on first?
