# Question: The appearance of bubbles in the plastic sheets produced by

The appearance of bubbles in the plastic sheets produced by Cumberland’s new extrusion equipment meets the Poisson conditions. The average number of bubbles per square yard of product is 0.2 (otherwise, the appearance of bubbles seems perfectly random and independent). Compute the

a. probability of fnding no bubbles in a randomly selected square yard of plastic.

b. probability of fnding two bubbles in a randomly selected square yard of plastic.

c. There is less than a 1% probability that a square yard of product will contain ____ or more bubbles.

d. If a full plastic sheet is six feet by nine feet, how likely that a randomly selected sheet will show three or more bubbles?
