Best ResponseYou've already chosen the best response.0hi ! okay so this is a question f conditional probability. the condition here is that the student chosen has a Y brand phone so our sample becomes 580 from 1000 ( because 580 students have Y brand phone) now we know that 80 students have both so the probability will be 80/580
