If you want to read Chnese,let me know.Here I can't put inChines

When we play a die ,Sample space={1,2,3,4,5,6}, P(i)=1/6, i=1,2,3,4,5 or 6.

Event E={1,2,3,}, F={2,6} G={3,4,5,6}.We say E and F are independendt as P(E*F)=P(2)=1/6

P(E)=1/2,P(F)=1/3. P(E)=1/2,P(E*F)=P(E)*P(F)=1/6.E and G are not...Why...?

Back to the star...,A,B,C<D,E,F ..as show up,a,b,c,d,e,f as not.

Sample space= {Adcdef,aBcdef,abCdef,abcDef,abcdEf,abcdeF,abcdef}

P(notA*notB)=P(notA)*P(notB)=.54....so,they are independent......

your Question not clear,..
