Crickets must have been introduced at the lambda = 2 is 20.
Given:
you observe 40 crickets on an island after crickets were first introduced 2 years ago , at the lambda = 2 how many number of crickets must have been introduced .
Let x be the crickets must have to been introduced.
Number of crickets = observed crickets / lambda value
we know that,
Observed crickets = 40
lambda value = 2
substitute these values
Number of crickets = observed crickets / lambda value
= 40 / 2
= 20 crickets.
Therefore Crickets must have been introduced at the lambda = 2 is 20.
