Answer 1

Answer #1

Solution: Let x be the number of cars arriving over five minutes of an interval. We are given that a random variable x follows the Poisson distribution with a mean of 3 cars. Therefore, we have:

X ~ Poisson (1= 3)

We are required to find the probability of 5 cars arriving over a five-minute interval.

PGC 5)_e3 PT = 5) = 6 0.049787068 x 243 = = 0.1008 120

Therefore, the correct option is 0.1008
