Use the Poisson Distribution to find the indicated probability.
-In one town, the number of burglaries in a week has a Poisson distribution with a mean of 1.9. Find the probability that in a randomly selected week the number of burglaries is at least three.
A) 0.8290
B) 0.1710
C) 0.7037
D) 0.1253
E) 0.2963

Question

Quizplus · Accepted Answer

The probability of having at least three burglaries is 1 minus the probability of having fewer than three. Calculate P(X < 3) using the Poisson formula for 0, 1, and 2, then subtract from 1.
