The mean number of automobiles entering a mountain tunnel per two-minute period is one. An excessive number of cars entering the tunnel during a brief period of time produces a hazardous situation. Assume that the tunnel is observed during seven two-minute intervals, thus giving seven independent observations Y₁, Y₂,..., Y7, on the Poisson random variable. Find the probability that Y> 2 during at least one of the seven two-minute intervals. (Round your answer to three decimal places.)
