Step by step solution please

{1} Estimating the Most Liker Location of Oxygen-Cathode Failure: The below table contains the failure-frequency map of identical oxygen cathodes in an Electl'ochemistrj,r experiment. These mutually independent failures are stipulated to have occurred in three independently operating electrochemical plants. Then answer the following: (a) Find the probability of human error in the experiment. (b) Which plant has most-likely failure {next time) by human error. (c) Which source-of-failure has least likely failure by plant 1. Number of cathode failures over a xed period of operation in different plants mm mm Catalyst surface area Pore volume Binder content Catalyst content Human error number of failures n_
