For any event E, P(E)+P(¯¯¯¯E)=1 where ¯¯¯¯E stands for 'not E'. E and ¯¯¯¯E are called complementary events
If E and F are events such that P(E)=14, P(F)=12 andP(E and F) =18 Find (i) P (E or F) (ii) P (not E and not F)
If E and F are events such that P(E) =, P(F) = and P(E and F) =, find:(i) P(E or F), (ii) P(not E and not F).
