Data was collected on bolt failures in solar panel connection. A large number of solar panel assemblies, each with the same number of bolts, were tested to find out whether each bolt was a success or a failure. The number of passing bolts in an assembly had a mean value of 5.3 and a variance of 2.65. If failing bolts occur randomly and independently, find the probabilities associated with possible numbers of passing bolts in an assembly. An assembly of solar panel is considered adequate if there is one or fewer bolt failures,what is the probability that a randomly chosen assembly will be inadequate?
