We do a survey of student devices. We find that 40% of students own a desktop computer, and 30% of students with a desktop also have a Playstation. Out of all students, 50% have a Playstation. a) What is the probability that a randomly chosen student has both a desktop and a Playstation? b)With the same conditions as #3, what is the probability that a randomly chosen student has a desktop, if we know they have a Playstation?
