Liwei has negotiated a deal with the vendor that an overall defect rate of 5% is acceptable. If more than 5% of the jars on a given skid are defective, Princess Foods Corporation does not have to pay for that shipment. If the defects are greater than 5%, that shipment is returned (at the shipper's expense).

If 12 samples of product are randomly selected and tested, what is the probability of the following:

1. Exactly one samples are defective
2. Between two and five inclusive are defective
3. Less than three are defective
