The number of knots in a particular type of wood follows a Poisson distribution with an average of 1.5 knots per 10 cubic feet of wood. Find the probability that a 10-cubic-foot block of wood has at least two knots. Round your answer to 3 decimal places.

5 per 10 cubic feet of wood. The probability of having k knots in a 10-cubic-foot block of wood is given by the Poisson distribution formula: P(k; λ) = (λ^k * e^-λ) / k! Where: - λ is the average number of knots (1.5 in this case) - k is the number of knots we Show more…
