DISTRIBUCIÓN DE PROBABILIDAD POISSON

Airline passengers arrive randomly and independently at the passenger check-in counter. The average arrival rate is 10 passengers per minute.

a. Calculate the probability that no passenger will arrive within one minute.

μ = 10 in 1 minute
x = 0 in 1 minute

b. Find the probability that three or fewer passengers will arrive within one minute.

μ = 10 in 1 minute
x ≤ 3 in 1 minute >>> P (x = 0) + P (x = 1) + P (x = 2) + P (x = 3)

c. That no passenger arrives within 15 seconds.

μ = 2.5 in 15 seconds
x = 0 in 15 seconds

People arrive according to a Poisson process with rate λ, with each person independently being equally likely to be either a man or a woman. If a woman (man) arrives when there is at least one man (woman) waiting, then the woman (man) departs with one of the waiting men (women). If there is no member of the opposite sex waiting upon a person’s arrival, then that person waits. Let X(t) denote the number waiting at time t. Argue that...
