The Poisson distribution is used to model the number of events occurring within a given time interval .
The formula for the Poisson probability mass function is
λ is the shape parameter which indicates the average number of events in the given time interval .
A company estimates that an average of 10 bulbs are defective every day during the final control of the bulbs it produces .
Calculate the probability that 4 bulbs will be defective on a control day using the Poisson distribution .
