| EVENT | Frequency |
| E1 | 20 |
| E2 | 12 |
| E3 | 18 |
Total frequency = 20+12+18 = 50
We know that the probability is defined as the ratio of favorable outcome and total outcome
So, P(E1) = (favorable)/(total outcome) = 20/50 = 0.40
Similarly
P(E2) = (favorable)/(total outcome) = 12/50 = 0.24
And
P(E3) = (favorable)/(total outcome) = 18/50 = 0.36
This method is known as relative frequency method, i.e. in this method we use relative frequency to calculate the respective probability.

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
