The number of plants that are found in a field averages 2 per square metre and follows a Poisson distribution. Based on this,
a. What is the expected value?
b. What is the probability that a 1-square metre section will contain less than 3 plants?

The Answer is a. The expected value of the Poisson distribution is E(X) = λ = 2.
b. P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2) = e-2

= 0.6767
