Two cards are drawn at random and without replacement from a pack of $52$ playing cards. Find the probability that both the cards are black.

From a pack of $52$ cards,two cards are drawn in succession one by one without replacement. The probability that both are aces is

Bag $A$ contains $4$ white and $2$ black balls, bag $B$ contains $3$ white and $3$ black balls, and bag $C$ contains $2$ white and $4$ black balls. If a bag is chosen at random and a ball is chosen at random from it, then the probability that the ball drawn is black is

$A$ bag contains $10$ similar balls,of which $4$ are blue and $6$ are red. Three balls are taken out at random from the bag one after the other without replacement. The probability that all the three balls drawn are red is

If two cards are drawn one after the other without replacement from a well-shuffled ordinary deck of $52$ cards, then the probability that both of them are aces is

From a pack of $52$ cards,two are drawn with replacement. The probability that the first is a diamond and the second is a king is:
