A patient fills a prescription for a 10-day regimen of two pills daily. Unknown to the pharmacist and the patient, the 20 tablets consist of 18 pills of the prescribed medica- tion and 2 pills that are the generic equivalent of the prescribed medication. The patient selects two pills at random for the first day's dosage. If we check the selection and record the number of pills that are generic, is this a binomial experiment?
