Based upon past experience, it is supposed that the number of flaws per foot in rolls of grade 2 paper follows a Poisson distribution with a mean of 1 flaw per 2 feet of paper (0.5 flaw per foot).
What is the probability that in a 1 foot roll, there will be at least 2 flaws?
What is the probability that in a 12 foot roll, there will be atleast 1 flaw?
