The number of telephone calls at a call center follows a Poisson distribution. Assume that on average there are 10 calls per hour. What is the probability that there are exactly five calls in an hour? O (e^(-10)*10^5)/5! (e^(5)*5^10)/1O! O e^(-10)/5!

The number of telephone calls at a call center follows a Poisson distribution. Assume that on average there are 10 calls per hour. What is the probability that there are exactly five calls in an hour? O (e^(-10)*10^5)/5! (e^(5)*5^10)/1O! e^(-10)/5! The number of telephone calls at a call center follows a Poisson distribution. Assume that on average there are 10 calls per hour. What is the probability that there are three or fewer calls in an hour? O (e^(-10)*10^3)/3! + (e^(-10)*10^2)/2! + (e^(-10)*10)/1! (e^(-10)*10^3)/3! + (e^(-10)*10^2)/2! + e^(-10)*10 + e^(-10) (e^(-10)*10^3)/3!
