The number of imperfections in a square yard of a certain material has a Poisson distribution with parameter \(\lambda = 4\). Find the probability that \begin{itemize} \item a 1-square-yard sample will contain at least one imperfection. \item a 2-square-yard sample will contain at most one imperfection. \end{itemize}

Step 1
To find this probability, we can use the complement rule. The complement of "at least one imperfection" is "no imperfections". The probability of no imperfections in a 1-square-yard sample is given by the Poisson distribution with parameter λ = 4: P(no Show more…

Let X be the number of imperfections per yard in a given type of fabric. Suppose X follows a Poisson distribution with mean λ = 0.25. 2 yards of fabric are to be inspected for imperfections. a) Find the probability that the 2 yards of fabric have at most 1 imperfection. b) Find the probability that the 2 yards of fabric have more than 2 imperfections.

3. In the inspection of a fabric produced in continuous rolls, the number of imperfections per yard is a random variable that has Poisson distribution given by with mean of 0.25. Find the probability that 4 yards have at most two imperfections.
