Let X be the number of lightning strikes in a year at the top of particular mountain.
X follows Poisson distribution with mean μ = 3.8
We have to find here the probability that in randomly selected year the number of lightning strikes is 0
The Poisson probability is given by,
P(X=k) = 
Here we have X=0, mean =3.8
Hence probability that X=0 is given by
P(X=0) = 
P(X=0) = 
P(X=0) = 0.0224
The probability that in a randomly selected year, the number of lightning strikes is 0 is 0.0224
Answer:
Alana is 13 years old.
Step-by-step explanation:
Assuming you meant Mazo = Maisel,
You start from the bottom:
Amelia is 10 years younger than 17-year-old Maisel.
Amelia is 7 years old. (17-10)
Ernie is 2 years older than 7-year-old Amelia.
Ernie is 9. (2+7)
Alana is 4 years older than 9-year-old Ernie.
Alana is 13 years old. (4+9)
Hope this helps!
