Question 1131524: A company purchases shipments of machine components and uses this acceptance sampling plan: Randomly select and test 23 components and accept the whole batch if there are fewer than 3 defectives. If a particular shipment of thousands of components actually has a 8% rate of defects, what is the probability of fewer than 3 defectives?

Look for 0,1,2 defectives
for 0:0.92^23=0.1469
for 1: 0.92^22*0.08*23 ways it can happen (23C1)=0.2939
for 2::23C2*0.92^21*0.0064=0.2811
This probability is 0.7219
