Answer 6

Look at it in a comparison between two sports.
65% football
70% volleyball
75% basketball
If you compare football and volleyball, the max of doign both sports is 65% and the min is P(volleyball)-P(not football) = 70% - 35% = 35%
So that's the min of the two sports.
Do the same for football and basketball.
Max is 65% once again, min would be 40%.
Therefore the smaller of the two favlues (40% and 35%) will be the smaller total.

The min of playing all three sports is 35%

venn diagrams are probably the best way to visualize these sorts of problems.
