His first day in office he proposed a tax break for Lilliputians who are either LittleEndians or have blue eyes, or both. What proportion of the Lilliput population would receive a tax break under his proposal? P( Little ∪ Blue ) = P( Little ) + P( Blue ) – P( Little ∩ Blue ) = 0.60 + 0.20 – 0.096 = 0.704 . OR P( Little ∪ Blue ) = P( Little ∩ Blue ) + P( Little ∩ Blue ' ) + P( Big ∩ Blue ) = 0.096 + 0.504 + 0.104 = 0.704 . OR P( Little ∪ Blue ) = 1 – P( Big ∩ Blue ' ) = 1 – 0.296 = 0.704 ....
