Use the Poisson Distribution to find the indicated probability.
-The number of lightning strikes in a year at the top of a particular mountain has a Poisson distribution with a mean of 3.8. Find the probability that in a randomly selected year, the number of lightning strikes is 0.
A) 0.0224
B) 0.0380
C) 0.0291
D) 0.0112

Quizplus · Accepted Answer

Using the Poisson distribution formula, with λ = 3.8 and x = 0:
P(X = 0) = (e^-3.8)(3.8^0)/(0!) = e^-3.8 ≈ 0.0224. Therefore, the answer is choice A.
