Cars arrive at a "Y" in a road and must choose either the left fork or the right fork. Assume that the number of cars that arrive at the fork has a Poisson distribution, the average number of cars that arrive at the "Y" per minute is 19, and a car arriving at the fork chooses the left fork with probability 8/19 and the right fork with probability 11/19. What is the exact formula for the Poisson distribution that gives the number of cars that travel down the right fork per minute?

Need help with Poisson distribution.

Cars arrive at a "Y" in a road and must choose either the left fork or the right fork. Assume that the number of cars
that arrive at the fork has a Poisson distribution, the average number of cars that arrive at the "Y" per minute is 19,
and a car arriving at the fork chooses the left fork with probability 8/19 and the right fork with probability 11/19.
What is the exact formula for the Poisson distribution that gives the number of cars that travel down the right fork
per minute? Your answer should be a function of k and should have an exponent of "e".
Warning: to type a factorial like k! in this problem, you need to type "fact(k)."
P(X = k) =
