The answer has something to do with volume.
Sorry I do t understand.............
the question
Answer:
Step-by-step explanation:
Given that the random variable x represents the number of phone calls an author receives in a day
Poisson distribution is a discrete distribution with random variable countable.
Here no of calls cannot be in fraction or decimal.
Also given that X is Poisson with mean = 7.6
X is discrete since no of phone calls can take values as 1,2,3....
X can take any value from 0 to infinity.
x=3.2 is not possible since 3.2 calls does not exist.
It would be: 4√6 + 5√6 = 9√6
In short, Your Answer would be 9√6
Hope this helps!
