Answer:

P(x < 3) = 0.42319

Step-by-step explanation:

From the given information:

The mean density \lambda = 3

Let x be the random variable that follows a Poisson distribution.

Therefore:

\mathtt{P(x) = \dfrac{e^{-\lambda} \lambda ^x}{x!}}     for x =1, 2, 3...

However, the probability that a random quadrat contains less than 3 spatuletails can be computed as:

\mathtt{P(x

\mathtt{P(x

\mathtt{P(x

\mathtt{P(x

\mathtt{P(x

P(x < 3) = 0.42319
