Answer:
The probability of no calls in a one-minute interval is 0.1353
Step-by-step explanation:
120 calls per hour gives 120/60 calls per minute.
Mean of calls per minute, λ = 2 calls/minute
Using Poisson distribution formula
P(X=x) = ((e^-λ)(λ⁻ˣ))/x!
For 0 calls in a minute,
P(X=0) = (e^-2)(2⁰)/0! = e(^-2) = 0.1353
Hope this Helps!!!
