Determine the indicated probability for a Poisson random variable with the given values of $\lambda \text { and } t \text {. }$ $\lambda = 0.8 , t = 4 , P ( \text { At least } 2 )$
A) 0.9592
B) 0.0408
C) 0.8288
D) 0.6201

Quizplus · Accepted Answer

The Poisson probability of at least 2 events is 1 minus the probability of 0 or 1 event. Calculate $P(X \geq 2) = 1 - (P(X = 0) + P(X = 1))$ using $\lambda t = 3.2$.
