-----------------------
Draw three interlocking circles; label them rock, rap, and jazz
------------------
Put a "3" in the intersection of all three circles
Move outward to the intersection of rap/rock-----put 22-3=19
Also mark the intersection of rock/jazz-----put 11-3=8
Marc the intersection of rap/jazz----?-3 =
----------------------
Keep moving to the outer limits of the circle, marking each section
based on the data you have and the entries you have made.
----------------------
Cheers,
Stan H.
