Probability Tes...

If A & B are two events such that $$p(A)\neq 0$$ & $$ P(B)\neq 1,t hen\ P(A'/B)$$

If A and B are two events, such that P(A or B)=P(A), then 

A and B are two independent  events such that $${ P\left( { A }^{ ' }\cap B \right) =\dfrac { 2 }{ 15 }  }$$then P(B) is equal to :

The probability of the sun setting in the west is..............

Let A and B be two events such that $$P(A) =7/20, P(B) = 9/20, P(A\cup B)=11/20$$ ,then the value of $$P(\bar{A}\cup B)$$ is equal to 

If truth value of $$p$$ is $$T$$ , $$q$$ is $$F$$ , then truth values of $$( p \rightarrow q )$$ and $$( q \rightarrow p ) \vee ( \sim p )$$ are respectively N/A

If A and B are such events that $$P(A)>0$$ and $$ P(B)\neq 1$$ then $$P\left(\dfrac{\bar{A}}{\bar{B}}\right)$$ is equal to-

A card is drawn from a well shuffled pack of 52 cards. Events A and B are defined as follows :
A : Getting a card of spade
B : Getting an ace, then A and B are .....

4 normal distinguishable dice are rolled once. The number of possible outcomes in which at least one dice shows up 2?

$$8$$ players compete in a tournament, every one plays everyone else just once. The winner of a game gets $$1$$, the loser $$0$$ or each gets $$\dfrac{1}{2}$$ if the game is drawn. The final result is that every one gets a different score and the player playing placing second gets the same as the total of four bottom players.The total score of all the players is
