Question 1066967: a local produce supplier has determined that 5% of its orders are sent out with items missing due to the availability of the produce. this week the supplier filled 340 orders. what is the probability that there were fewer than 10 were sent out incomplete?

Can use the normal probability approximation with this binomial, since np and n(1-p) >5
np=mean=0.05*340=17
sqrt (np*(1-p))=sqrt (17*0.95)=sqrt (16.15)=4.02
z=(10-17)/4.02=0.0408.
