Question

on average, jakob has noticed that 18 trains pass by his house daily (24 hours) on the nearby train tracks. what is the probability that at most 4 trains will pass his house in a 6-hour time period? (round your answer to three decimal places.)

Answer 1

Explanation:

The time interval of interest is 6 hours

There is an average of 18 trains per 24 hours or 18/(24/6)=49/12 trains per 6 hours.

The probability can be found using the Poisson distribution with parameter

λ=49/12
