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!

Transcribed Image Text: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!
