For Quality Control Purposes, a Company That Manufactures Sim Chips

For quality control purposes, a company that manufactures sim chips for cell/smart
phones routinely takes samples from its production process. Since it is important that
these chips are nearly fault free, one inspection check involves using microscopic
equipment to count the number of imperfections on each chip. Suppose the average
number of imperfections per 1000 sim chips is 3.
A. What is the probability that a sheet of this size has 2 imperfections?
b. What is the probability that a sheet of this size has no more than 2 imperfections?
c. What is the probability that a sheet half this size (18 sq. ft.) has 2 imperfections?
