A company is about to launch a new cell phone model. In the past, 40% of its cell phones have launched successfully. Before any cell phone is launched, the company conducts market research and receives a report predicting favorable or unfavorable sales. In the past, 70% of successful cell phones and 20% of unsuccessful cell phones received favorable reports. What is the probability that the new cell phone will receive a favorable report, given that the cell phone launch is successful?
P(favorable report | successful launch) = P(favorable report and successful launch) | P(successful launch) where P(favorable report and successful launch) = (0.40)(0.7) (according to the #'s in the problem) P(successful launch) = (0.4) plug into the original equation and solve for P(favorable report | successful launch)
