Question

The number of calls received by an office on Monday morning between 8:00 AM and 9:00 AM has a mean of 6. Calculate the probability of getting no more than 1 call between eight and nine in the morning. Round your answer to four decimal places.

Answer #1

Answer : **The probability of
getting no more than one 1 call between eight and nine in the
morning is 0.0174**

**...**

**Also note that, probability
of event " no more than " is same as the event " at most
".**

. A hotel’s reservation center receives 180 calls on average
from 9:00 AM – 10:00 AM, and the number of calls in that hour can
be modeled by a Poisson random variable. (a) (8 pts) Find the
probability that more than one call come in the one-minute period
9:26 AM – 9:27 AM. (b) (8 pts) Find the probability that the first
call after 9:00 AM actually comes in after 9:02 AM.
