If `bar(E)` & `bar(F)` are complementary events of events E&F respectively then `P(E/F)+P(bar(E)/F)`

If bar(E) and bar(F) are the complementary events of E and F respectively and if 0

If E and F are the complementary events of events E and F, respectively,and if 01, then P((E)/(F))+P((E)/(F))=(1)/(2)bP((E)/(F))+P((E)/(F))=1cP((E)/(F))+P((E)/(F))=(1)/(2)dP((E)/(F))+P((E)/(F))=1

For two events, A and B, it is given that P(A) = (3)/(5), P(B) = (3)/(10) , and P(A|B)= (2)/(3) . If bar(A) and bar(B) are the complementary events of A and B, then P(bar(A) |bar(B)) equal to ?

If A and B are any two events such that P(A uu B) = 3/4, P(A nn B) = 1/4 and P(bar(A)) = 2/3 , where bar(A) stands for the complementary event of A, then what is P(B) ?

If E and F are two independent events and P(E)=1/3,P(F)=1/4, then find P(EuuF) .

Prove that if E and F are independent events, then so are the events E and F.

If E_(1),E_(2), are two events with E_(1)nn E_(2)=phi then P(bar(E)_(1)nnbar(E)_(2))=

If E and F are two independent events then prove that E' and F' are also independent.
