Find the probability that when a hand of $7$ cards is drawn from a well-shuffled deck of $52$ cards,it contains at least $3$ Kings.

If the letters of the word $SUCCESS$ are rearranged,what is the probability that all identical letters come together (in $/35$)?

If three cards are drawn randomly from a pack of $52$ playing cards,then the probability of getting exactly one spade card,exactly one king,and exactly one card having a prime number is

$\omega$ is a complex cube root of unity. When an unbiased die is thrown $3$ times,if $\beta_1, \beta_2, \beta_3$ are the numbers appeared on the die,then the probability that $\beta_1, \beta_2$ and $\beta_3$ satisfy $\omega^{\beta_1}+\omega^{\beta_2}=-\omega^{\beta_3}$ is

If the letters of the word "$ASSASSINATION$" are arranged at random in a row,then the probability that no two $A$'s come together is equal to

$3$ balls are drawn one after the other without replacement from an urn containing $4$ red,$5$ blue and $6$ yellow balls. The probability of getting three different coloured balls is
