Answer:
The likelihood that the number of drivers is at most 18 is 0.381.
Step-by-step explanation:
We are provided with the following details in the question:
The quantity of drivers traveling between a specific origin and destination in a set time frame follows a Poisson distribution characterized by the parameter μ = 20.
- The Poisson distribution defines the probability of a certain number of events taking place over a specific period, based on the mean frequency of those events.
- The variance for the Poisson distribution matches its mean value of Poisson distribution.
a) P(number of drivers will be at most 18)
Equation:


So, 0.381 represents the probability that the number of drivers will be at most 18.
For a 560-mile journey, Mrs. Allan's car will require 20 gallons of fuel. Meanwhile, Mrs. Owen's vehicle will need 16 gallons for the same distance.
For Mia's calculations, she should use y first because y signifies 22, while x indicates 4 dollars earned weekly.
40 tens converts to how many hundreds? The calculation is 40 multiplied by 10, resulting in 400.
