the army discovered that a recent shipment of grenades (both live and practice) had some labels inadvertently misapplied as to which case contained each kind. The manufacturer assured them that only 3% of the cases were labeled wrong. In a sample of 8 cases, what is the probability that no cases were labeled wrong:
