Minchanka [31]

Answer: \dfrac{1}{5525}

Step-by-step explanation:

The total number of cards =52

The number of kings in the cards = 4

If repetition is not allowed , then the total number of ways of choosing 3 cards will be :-

52\times51\times50=132600

The number of ways of choosing 3 kings will be :-

4\times3\times2=24

Now, the probability of choosing 3 king cards will be :-

\dfrac{24}{132600}=\dfrac{1}{5525}

Hence, the  probability of choosing 3 king cards  =\dfrac{1}{5525}
