Consider an example of grading a student in a university. The grading is

done as below:

$\begin{array}{cc}\text{A}\text{v}\text{e}\text{r}\text{a}\text{g}\text{e}\text{m}\text{a}\text{r}\text{k}\text{s}& \text{G}\text{r}\text{a}\text{d}\text{e}\\ 90-100& A+\\ 75-89& A\\ 60-74& B\\ 50-59& C\\ \text{B}\text{e}\text{l}\text{o}\text{w}50& \text{F}\text{a}\text{i}\text{l}\end{array}$

The marks of any three subjects are considered for the calculation of

average marks. Scholarships of $$1000$ and $$500$ are given to student s

securing more than $90\%$ and $85\%$ marks, respectively. Develop a

cause effect graph, decision table, and generate test cases for the above

scenario. solve in this order first specify causes and effects then draw a cause$-$effect graph then convert graph to descion table then create test cases from descion table
