QUESTION 3On the main form the btnQ3Click procedure opens the form frmQuestion3. Open the unit Question3_u.For this question you may NOT use SQL statements.   VRAAG 3 Maak die btnQ3Click-prosedure op die hoofvorm frmQuestion3 oop. Maak die eenheid (unit) Vraag3_u oop. Vir hierdie vraag mag jy NIE SQL-stellings gebruik nie.   3.1) Complete the btnQ3_1Click procedure.Using Delphi code filter the events table to determine how many under 20’s there were in the 2016 Olympics.
