Let x be the number of tree seedlings in a randomly selected one square meter plot in a forest. Suppose that x has a Poisson distribution with λ = 5, which corresponds to an average of five seedlings per square meter. Find the probability that a randomly selected one square meter plot contains no seedlings.
Sol:
X~number of tree seedlings in a randomly selected one square meter plot in a forest.
mean= λ = 5
P(X=0)
By poisson distribution P(X=x)=e^- λ* λ^x/x!
x=0 and λ=5 given
P(X=0)=e^-5*5^0/0!
=0.0067
ANSWER:0.0067

6. For a certain section of a pine forest, the number X of diseased trees per acre has a Poisson distribution with mean λ = 5. (C) Suppose we have 4 plots of forest, each one acre in size, giving 4 independent Poisson random variables, X1, X2,..., X4 with mean λ = 5. Find the probability that at least two of the plots of forest have 2 or more diseased trees per acre.
