A manufacturer of audio equipment inspects a portion of all parts they order from new suppliers. A new shipment has 10 parts, 4 are examined. It turns out that if 1 or more are defective, the batch will be rejected. What kind of distribution should you use?

I narrowed it down to binomial probability distribution or the poisson distribution.

Please help me with this little hang up so I can study for my test tonight. THANKS!!
