Conditionality And Grouping

Introduction Conditions are given based on which the action takes place. There are four basic conditions. Based on them the decisions are made. Based on this conditions the groups are formed.

Conditions If A occurs then B also will occur
If A occurs then B will not occur If A has not occurred then B will occur If A has not occurred then B also will not occur
