(a) For a compressor the probability of failure occurring during a given week is given in Table Q5(a). (1) Calculate the Annual Breakdown Maintenance Costs (where no Preventive Maintenance is carried out). The costs are 300 OMR to repair the compressor, every time it fails. (ii) Preventive maintenance costs 60 OMR for each service. Calculate if Preventive Maintenance is cheaper than Breakdown Maintenance, and if so how often Preventive Maintenance should be carried out. There are 48 working weeks in a year. Table Q5(a) Probability of failure during the given week Week of Operation 0.00 0.15 3 0.15 4 0.30 0.40

Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
