Equation transcription:
Text transcription:
P(|Y-\lambda| \leq 2 \sigma
ANSWER:Solution:
Step 1 of 3:
It is given that the number of accidents per month Y is a Poisson random variable with mean 6.
Then the probability mass function of Y is
P(Y)=
Using this we need to calculate P(|Y-|) and then we have to compare it with the empirical rule.
