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}

valkas [14]

Answer:

Step-by-step explanation:

a = 27

n = 20

d = -5

L20 = 27 + (n - 1)*d

L20 = 27 + (20-1)*_5

L20 = 27 + 19*-5

L20 = -68

Sum = (a + L)*n/2

Sum = (27 - 68)*20/2

Sum = -41 * 10

Sum = - 410
