Event and sample space

If A an event in a sample space S, then

If A be any event in sample space then the maximum value of 3sqrt(P(A))+4sqrt(P(barA)) is :

Statement-1 If A and B be the event in a sample space, such that P(A)=0.3 and P(B)=0.2, then P(Acapoverline(B)) cannot be found. Statement-2 P(Acapoverline(B))=P(A)+P(overline(B))-P(Acapoverline(B))

If A and B are two events of sample space S and P(A)!=0 then P(B/A)=

If A and B are mutually exclusive events in a sample space S, then

If A and B are any two events in a sample space S then P(A uu B) is

If A and B are two independent events in a sample space S, then : P(A//B')=

If A, B, C are pair-wise mutually exclusive, and exhaustive, events of a sample space S, then P(A) + P(B) +P(C) =
