A company needs to submit 54 prototype assemblies to a new customer. To accomplish this, each of their 6 team members builds 9 units each. Unfortunately, one team member did not follow instructions and his assemblies will not work in the field.

If the customer samples 13 assemblies for Quality Control, what is the probability that they will not have one of the defective units in their sample?
