- Set union - union of two relations
- Set difference - minus operation on two relations
As we can see, Join is not part of the basic set operations but it is implemented using the Cartesian Product operator.
Answer: Probability/impact risk matrix
Explanation: Probability/impact risk matrix is type of matrix that defines the probability as well as impact that depicts whether the risk is low ,high or moderate.
Impact matrix is sort of tool which helps in conversion of any plan into a action. Probability matrix help in defining the chances in defining the risk.The positioning of the impact value of risk is plotted on the vertical axis and performance value on the horizontal axis.
Thus probability/impact matrix is the correct tool for the problem mentioned in the question.
