The Poisson mass function is often used in biology to model the number of bacteria in a solution. Suppose a dilute suspension of bacteria is divided into several different test tubes. The number of bacteria x in a test tube has a Poisson mass function with a parameter 2 that represents the mean number of bacterial cells contained in the different test tubes. Express the probability that a particular test tube contains no bacteria, in terms of .

The Poisson mass function is often used in biology to model the number of bacteria in a solution. Suppose a dilute suspension of bacteria is divided into several different test tubes. The number of bacteria \( x \) in a test tube has a Poisson mass function with a parameter \( \lambda \) that represents the mean number of bacterial cells contained in the different test tubes.

Express the probability that a particular test tube contains no bacteria, in terms of \( \lambda \).
