Question 1141190: A random sample of 250 adults found that 67% of them access the internet at work, 82% of them access the internet at home and 60% access the internet both at home and work. What is the probability that a randomly selected adult will access the internet at home or at work?

P(home or work) = P(home) + P(work) - P(home and work)

P(home or work) = 82% + 67% - 60% = 89%
