n a call center the number of received calls in a day can be modeledby a Poisson random variable. We know that, on average, 0.5% of days the callcenter received no calls at all. What is the average number of calls per day

Number of calls in a day is distribution pois (ln (200)

Step-by-step explanation:

Let X be the number of received calls in a day, I. e X~poisX

P (X=0) = e~^=1/200 = ^. our=in (200)

Answer:Pois (ln (200))

Step-byy-step explanation:

Let N be the number of received calls in a day

That is

N∼Pois (λ).

0.5% = 0.5/100 = 1/200 of no calls

P (N=0) = e^-λ=1/200

-λ=e^ (1/200)

λ=in (200)

Our number of calls in a day is distributed Pois (ln (200)).
