Extracted text: Two underground mines are to be compared to each other in terms of Fatality Injury Frequency Rating (FIFR). In mine A, yearly production is 12 million tonnes of ore and the number of fatality is 3. In mine B, yearly production is 4 million tonnes of ore and the number of fatality is 2. The equation is: FIFR=(Number of Fatalitiesx10)/(Yearly tonnage) What is the interpretation based on FIFR? O a. Both of them are very bad equally. O b. Both of them are very good equally. OC Mine B has a better rating. Od. Mine A has a better rating. O e No comparison can be made by using FIFR because the productions are not equal to each other.
