3. Find P(S|T)
4. Find P(S^C)

Intent! to take the Don't Intend to TOTAL AP exam, T take the AP exam Seniors, 5 17% 63% 80% Who are not 7% 13% 20% seniors TOTAL 24% 75% 00% ) "' PLOTI'ING THE DATA IN A TABLE, WE CAN SEE THAT THE TOTAL WILL ALWAYS BE 100% REPRESENTING THE TOTALITY OF THE POPULATION. S=63% 17% T= 7% Seniors Seniors Intending who intend to take to take AP 13% AP exam exam NEITHER SENIORS NOR INTEND TO TAKE THE AP EXAM VENN DIAGRAM 80% ARE SENIORS BUT A PART OF IT WHICH IS 17% ARE SENIORS ALSO THAT INTEND TO TAKE THE AP EXAM; THIS IS THE INTERSECTION.
