Age Adult Population, % Group Who Are Renters, % 21-44 48 62 45-64 27 38 65 and over 25 65 (a) What is the probability that an adult selected at random from this population is a renter?   (b) If a renter is selected at random, what is the probability that he or she is in the 21-44 age bracket?   (c) If a renter is selected at random, what is the probability that he or she is 45 years old or older?

Students taking the Graduate Management Admissions Test (GMAT) were asked about their undergraduate major and intent to pursue their MBA as a full-time or part-time student. A summary of their responses follows. Undergraduate Major Intended Enrollment Status Full-Time Part-Time Intended Enrollment Status Full-Time Part-Time Totals 514 a. Develop a joint probability table for these data (to 4 decimals). Totals Business 344 170 Engineering 200 Business 169 I 369 Undergraduate Major Engineering Other Other Totals 238 782 196 434 535 1,317 Totals b. Use the marginal probabilities of undergraduate major (business, engineering, or other) to comment on which undergraduate major produces the most potential MBA students. Select your answer - + c. If a student intends to attend classes full-time in pursuit of an MBA degree, what is the probability that the student was an undergraduate engineering major (to 4 decimals)? d. If a student was an undergraduate business major, what is the probability…
