A manufacturing company produces 10,000 plastic glasses per week. This company supplies plastic glasses to another company, which packages the glasses as part of picnic sets. The second company randomly samples 10 glasses from the supplier. If at least eight of the sampled glasses are non-defective, the second company accepts the lots. What is the probability that the lot will be not accepted if the glass manufacturing company is producing glasses that are 90% non-defective?
