Answer:
So, the probability is P=0.0097.
Step-by-step explanation:
We know that the number of flaws in a certain type of lumber follows a Poisson distribution with a rate of 0.45 per linear meter.
We conclude that λ=0.45.
We use the Poisson formula:

We calculate the probability that a board 3 meters in length has no flaws. We get that k=3.
We calculate:

So, the probability is P=0.0097.
