A university student frequents one of two coffee houses on campus, choosing Tim Hortons 80% of the time and Starbucks 20% of the time. Regardless of where she goes, she buys a decaffeinated coffee on 90% of her visits. (a) The next time she goes into a coffee house on campus, what is the probability that she goes to Tim Hortons and orders a decaffeinated coffee? (Enter your answer to two decimal places.) ✓ 0.72 (b) Are the two events in part (a) independent? Explain. O Yes, because the probability that the student orders a decaffeinated coffee is 0.9 regardless of whether the student visits Tim Hortons or Starbucks. O No, because the probability that the student orders a decaffeinated coffee depends on whether the student visits Tim Hortons or Starbucks. (c) If she goes into a coffee house and orders a decaffeinated coffee, what is the probability that she is at Starbucks? 0.0278 x
