Step-by-step explanation:
consider the histogram carefully and answer.
If you turn all the numbers into decimals it becomes, -6.25, -6.35, -6.20, and, 6.1 so in order it would go 6.1, -6.20, -6.25, -6.35
Answer: Our required probability is 0.384.
Step-by-step explanation:
Since we have given that
In 24 hours,
λ = 20
In 6 hours,

As we know that it is a Poisson distribution.
E[X] = λ = 5
Probability that more than 6 trucks will pass her apartment is given by

Hence, our required probability is 0.384.
