A company produces 10,000 plastic papers per day. This company supplies papers to a shops which sells them in packs of 10 papers per pack. If less than two of a randomly selected pack (of 10 papers) from the order are defective, the shop accepts the whole order. The proportion of defective papers produced by the manufacturing company is 10%. Let ? be the random variable representing the number of defective papers in a pack.   What is the probability that a randomly selected pack (of 10 papers) has more than two defective papers?

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
