Question 1124603: At a local University, 57.8% of the incoming freshman have a computer. If 8 students are selected at random, find the probability that none have a computer. Answer by ikleyn(52782) (Show Source):
From the condition, 57.8% students have a computer - hence, the rest 100% - 57.8% = 42.2% do not have a computer.
So the probability that the student selected at random has no computer is 0.422.
Then the probability that no one of 8 students selected at random has a computer is = 0.001 (approximately).
