The answer that you have is most likely right, since the grouping did not change.
First option because 3 x 10^9 is 3,000,000,000
Answer:
Let X the random variable that represent the number of emails from students the day before the midterm exam. For this case the best distribution for the random variable X is
The probability mass function for the random variable is given by:
The best answer for this case would be:
C. Poisson distribution
Step-by-step explanation:
Let X the random variable that represent the number of emails from students the day before the midterm exam. For this case the best distribution for the random variable X is
The probability mass function for the random variable is given by:
And f(x)=0 for other case.
For this distribution the expected value is the same parameter
And for this case we want to calculate this probability:
The best answer for this case would be:
C. Poisson distribution
If you round it to the nearest pound it is 1.1 kg
2.5/2.2 = 1.13....
