$A$ box contains $2$ black,$4$ white and $3$ red balls. One ball is drawn at random from the box and kept aside. From the remaining balls in the box,another ball is drawn at random and kept aside the first. This process is repeated until all the balls are drawn from the box. The probability that the balls drawn are in the sequence of $2$ black,$4$ white and $3$ red is

In a game of cards,what is the probability that a specific player holds all $4$ kings in a hand of $13$ cards?

Among $15$ players,$8$ are batsmen and $7$ are bowlers. Find the probability that a team of $11$ players is chosen consisting of $6$ batsmen and $5$ bowlers.

$A$ cricket team has $15$ members,of whom only $5$ can bowl. If the names of the $15$ members are put into a hat and $11$ are drawn at random,then the probability of obtaining a team of $11$ containing at least $3$ bowlers is
