Hello i hope you are having a good day :) Question : Suppose 67% of all teenagers own a laptop and 29% of all teenagers own a laptop and a tablet. What is the  probability that a teenager owns a tablet given that the teenager owns a laptop?  19%  38%  43%Firstly you would do the vent of teenagers that has a laptop would be A) 67% and then the both devices would be  B) 29% and then the one with the C) tablet you would do P(CIA) = B/A that would be 29/67 so it would equal 0.43 which means it would be 43 percent.  Hopefully that helps you :)
