Answer:
3 people
Step-by-step explanation:
The Poisson distribution is often used to model the number of times an event occurs in a specified time or interval.
It is given that on average 4 people arrive in one hour
How many people do you expect to arrive during a 45-minute period?
45 minutes corresponds to 3/4 or 0.75 of an hour
λ = E(X) = 4*0.75 = 3
Therefore, 3 people are expect to arrive during a 45-minute period.
