If `P(A)=(x)/(21)` and `P(barA)` is `11/21`. Find x.

If P(AuuB)=3//4 and P( barA )=2//3 , then find the value of P( barA nnB)dot

If P(AuuB)=3//4 and P( barA )=2//3 , then find the value of P( barA nnB)dot

If P(A) -P(barA)=0.2 , find P (A).

If P(AuuB)=3//4a n dP( barA )=2//3 , then find the value of P( barA nnB)dot

If P(A): P(barA)=3:7 , then P(barA)=0.3

If the events A and B are independent and if P(bar(A) ) = (2)/(3) , P(bar(B)) = (2)/(7) , then P(A cap B) is equal to a) 4/21 b) 3/21 c) 5/21 d) 2/21

If A and B are mutually exclusive events and if P(B) = (1)/(3), P(A cup B) = (13)/(21) , then find P(A)

If A is an event of a random experiment such that P(A) : P(barA) = 7:12 then find P(A).
