Trucks are known to arrive according to a Poisson distribution at a given weight station (checkpoint along a highway to inspect vehicular weights). Trucks are counted in 5-min intervals, and count data (number of trucks in 5-min intervals) are taken in 2,000 of these time intervals. It is noted that no trucks arrive in 100 of these 2000 intervals.

a) What is the probability of observing between 5 and 7 trucks?
b) With the same information, estimate the % of headways that are between 15 and 30 seconds (7 points)

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
