If A is a certain event, then what is the value of P(A) + `P(A^C)`?

If A is an impossible event, what is the value of P(A)?

If n(A)=2,then find the value of n(P(A))

If barE denote the complement or negation of an event E, what is the value of P (E)+P(barE)

Ifa,a-2 and 3a are in A.P., then the value of a is:

If p propq and when p=6 then q=30. Now if p=2, then what is the value of q?

If A and B are two indepent events, then (Fill in the blank). P(A cap B) = _____

If for any event E,P(E)=0.01,then find the value P(barE) when (barE) means "an event of not happening E"

If A,B and C are three mutually exclusive and exclusive and exhaustive events and 3P(C )=2P(A)=P(B) , then find the value of P(C ).

If A and B are two events not mutally exclusive and P(A) = 1/4, P(B) = 2/5, P(AuuB) = 1/2 Find P(A^C uuB^C)

If A and B are independent events such that P(A) = 3/10 and P(B) = 5/7 , Find P(A nn B)
