At 100 university campuses, 1,200 full-time undergraduate students were surveyed on their credit card usage. Among third-year students, 65% reported that they didn't have a credit card in their own name, and 23 % reported that they had at least one credit card in their own name and they paid their credit card balance in full each month. [Source: Glater, J.D. (2008, December 31). The debt trap: Colleges profit as banks market credit cards toa students. The New York Times.] Consider this random experiment. A university third-year student is randomly selected. The third-year student is interviewed and then categorised into ane of the fellowing three categories: she does not have a credit card in her own name, she has at least one credit card in her own name and pays her credit card balance in full each month, or she has at least one credit card in her own name and maintalns a credit card balance.

F The third-year student has at least one credit card in her awn name and pays her credit card balance in full each month e The third-year student has at least one credit card in her own name and maintains a credit card balance mutually exclusive The events O and C are exhaustive The events O, C, and B are a simple event Event C The set s-o, c, B is the correct description of the sample space for the random experiment because the events in 5 mutually exclusive and exhaustive are Find P(B) and P(C), and enter the probabilities in the following cells: P(B) P(C) = Session 5513 Timeout
