Please help me to solve the question i just posted
If you draw the Venn diagram, it should be clear how many like which sports and combinations. Where do you get stuck?
I stucked at where is talking about 9 liked football only downwards
Draw your Venn diagram with circles for
Football (F) upper left
Volleyball (V) upper right
Hockey (H) below, in the center
Now, the three portions on top should read 9, 6, 3
The center triangle reads 6
and the H only part reads 2
Since F=24, the F&V part must be 4
Since V=21, the V&H part must be 7
Now all the various sections are filled in and you can answer the questions.
