Question

Suppose a shipment of 160 electronic components contains 3 defective components. to determine whether the shipment should be​ accepted, a​ quality-control engineer randomly selects 3 of the components and tests them. if 1 or more of the components is​ defective, the shipment is rejected. what is the probability that the shipment is​ rejected

Answer 1

0.00067% chance it will be rejected.
The probability of each event occurring multiplied together will give us the total probability of one item being defective found in the 3.
1st 
3/160
2nd
3/159
3rd
3/158 
$\frac{3}{160} * \frac{3}{159} * \frac{3}{158} = \frac{27}{4019520} =0.0000067$
