The number of calls into a call center for any given interval often follows a Poisson distribution. The Poisson distribution is a discrete probability distribution char- acterized by a single mean parameter, λ. The Poisson distribution has a unique property that its variance is equal to its mean. Suppose the number of calls into a call center for any particular day follows a Poisson (10) distribution (i.e., a Poisson distribution with λ = 10). Calculate the probability that call center averages 12 or more calls per day over a span of 7 randomly selected days.
