Ok, I'll just start this one. There are

66 choose 4 samples. yes/no?

What is the P of 0,1,2,3,4 defecives in a sample? You need to caluclate these. I wouldn't be surprised if there's a sample or formula for this problem in your text. Look there first.

Looks like my observation skills are sliding. You only want to know the P that all of them are defects. So I don't think you should need to do as much calculating as I thought.
