Hi again...This is my last question for today.(adsbygoogle = window.adsbygoogle || []).push({});

I know that i send a lot of threads but...i dont have anyone else to help me.

Most of the times i dont send any solutions.I try but sometimes i dont understand and so...i dont have something to write.I post frequently

because if i dont give a 50% of correct answers i will not have the chance to write in the final exams...its a stupid rule.

My last 2 questions for today are.

1.We must prove that if P(A/B)=1 then P(B compl. / A compl.)=1

i wrote a lot of things but ..i didnt prove nothing : ~)

2.A and B are two events with non zero probabilities.

I must show (prove) if the following are i)correct,ii)faulse iii)correct under some conventions.

a)if A and B are foreign then they are independent (i dont know if this is the correct word) butif they are foreign P(A[intersect]B)=[empty-set]

b)if A and B are independent then they are foreign

c)P(A)=P(B)=0.6 A,B are foreign

c)P(A)=P(B)=0.6 A,B are independent
